Of course he is worth saving! His troubles are apparent to me, just based on his social media posts. I don't judge him for that stuff, he reminds me of my brother, who has Aspergers syndrome. My brother really turns people off (lol) but I know his good traits too. I wanted to suggest that because you have legal guardianship of Lucas (right?), you may be entitled to his medical activity, whereabouts, etc. If you have to travel to the hospitals or jails or anything, be sure to take your legal paperwork with you! I have guardianship of two nieces and I've learned to have that court order on me for anything related to them. Best wishes!
I read all his posts. We talked about them and he told me, grandma, I didn't mean that stuff. I just wanted people to talk to me.
I know my boy. He is a good but troubled young man. But worth finding. Worth saving.
