I'm sorry Blue
So many people are caught up in their own mess that they literally cannot see someone in need right in front of them. Maybe your young son is picking up on the stress too.
I know in my situation I can keep a preety good juggling act going and balanced by my ADD meds, but I have learned recently that when life tosses a bunch of extra things at your juggling act, thengs start to fall. My anxiety takes over, I'll be exhausted yet not able to sleep, then the sleep deprivation really takes a toll.
Please lean on us here, vent away... I know I did a few months ago and PC helped me when I had nobody to talk to irl.
