The fact, she appears to be remorseless is ASPD. Those of us that have BPD do HAVE remorse.
We do tend to lack empathy to varying degrees, which is different from remorse. It will be different with everyone. I'd say mine are on the low end of the spectrum. If you were to post that your best friend or dog died there are those that would empathize with you by what they say/feel. I know logically what to say, but I wouldn't feel anything. What comes naturally for most doesn't for me. Depending on the circumstance I'd have to think whether or not I'd feel anything. I can't always tell. This does NOT equate to being heartless. I'll still say what is appropriate, but inside I may not feel anything at all or care. This is making me sound bad. I wouldn't find happiness or joy in your pain. I'm just not in touch on an emotional level. I'm not sure how else to explain this but feel free to ask questions if you like.
Sociopath would fall under ASPD.
This is true.
No. BPD is a Personality Disorder, and Manic Depression would be a Mood Disorder.
There is Dialectical Behavior Therapy (DBT), Mentalization Behavior Therapy (MBT), and Schema. I'm not very familiar with either MBT or Schema, because it's hard to find these programs. I've been through DBT and even that can be hard to find a program but much easier to find then the other two. I think studies have shown that DBT has about a 60% success rate.
The idea is to replace dysfunctional coping skills with more functional/healthy ones. The keyword would be "skill". It takes a lot practice at working these skills into your life to where they become more natural and less thought about. The course is useless if the person doesn't want to put in the effort. It's 6 months long, but most will take it for a minimum of a year. That's the length of time it takes for it to be really beneficial.
It has helped in some areas of my life, but I've also become VERY detached which I suspect, is in part, because of dbt. Because, I'm detached I don't have the intense emotional interpersonal craziness (lol). It's still a dysfunctional way in which to cope though because I've closed myself off emotionally to others. It's a way to protect myself from the pain that comes from the emotional intensity that will eventually manifest in relationships/friendships and ultimately leading to the ending of those relationships/friendships.
You will hear/read from those without bpd talk about how heartless we are, and evil, and don't care about the ones we hurt as if we enjoy it. Those are the people that have typically been in some sort of relationship/friendship with someone who has bpd. They can't be further from the truth. The truth is we are aware of the emotional pain that we inflict in relationships, and just like they are hurting emotionally, so are we. We want "normal" relationships, and hate ourselves for being the way we are. We are not having fun, we are not enjoying the pain we are causing others, and we are not evil.
We are not all the same. My personality traits are not necessarily going to be the same as someone else with bpd. There are other factors that come into play such as I have major depression, and a mild form of ptsd. Someone else may have bpd with bi polar etc. There are some of us where the bpd effects only relationships, and others (like me) where it effects friendships and relationships. I'm assuming mental health wise you are "normal", it's like me asking you if all "normal" people are angry all the time because some are. All people are different.
If you were to be around me or another person with bpd it's unlikely that you would know we have it until you became closer to us, and even then it would depend on the person. You'd probably never see it with me, because I'm closed off emotionally. It's kind of like if you're around me fine and if not that fine too. It doesn't matter to me one way or the other. That does NOT mean that I'm going to be mean to you. I'd be nice, and I'd enjoy being around you or whoever otherwise I'd say no. All it means is I'm not going to have any kind of emotional attachment.
I'm sure some do, but probably most don't because they have some other underlying issue like major depression, bi polar etc.
This is true, and at some point it will catch up to them. for ie. go off of anti depressants it's likely they will have a depressive episode.
She appears to be remorseless which is a trait of ASPD. It's possible she may have traits of several disorders, but not enough traits to diagnose her with any specific personality disorder. In that case she would be pd-nos, which is personality disorder non specific.
Personality Disorders can be hard to diagnose even for Psychiatrist/Psychologists, and a good one won't immediately diagnose someone with a personality disorder. The problem with lay people copying and pasting the bpd (or any other pd) is that the trait has to be applied in the correct context and the personality disorder has to be looked at as a whole, and not just individual components. Because someone has intense anger does not mean they have bpd. It's possible they just have anger issues. Things have to add up.
Yes and no. A person with a mood disorder (ie. depression) is more likely to be hereditary, but it could also be from environmental factors. A personality disorder is a learned dysfunctional method of coping with some sort of traumatic event occurring in childhood. It becomes ingrained into our personality, because that is how we learn to cope.
There are no meds to cure or treat a personality disorder, however meds are usually prescribed to treat some other underlying symptom ie. anxiety. I don't know enough about other personality disorders, but with borderline I believe it can go into a state of remission if they have the appropriate therapy like dbt. I'm not sure we're ever really cured. I'm undecided, but lean towards no with other mental illness
If you want to know what dbt is like you can look at
www.dbtselfhelp.com it's the entire dbt course online.
Everyone just agrees he's the best looking man on the planet, right?
