Lots of love and respect to you. I'm worried about you myself- you seem to be the glue that holds people together. Please please take good care of yourself, husband, and son. If you can, take a beach day together or investigate an old fort, picnic lunch, go on a hike, etc.
Just get out for awhile, just the three of you, ok? You all need some peace, even if it's just for an afternoon. If possible, drive away about 2 hours to some fun place where you three can just chill and have fun. You all deserve this. You cannot be strong for Jamie if you don't take care of yourself first, to which a "mental health" day will do you the world of good. Just go, and have a good time with one another. When you get back, reality will still be there, but that little break will do you all the world of good.
We're always here if you need anything. Lean on us.
