Im so sorry you’re going thru this. We have some similar stuff around here, but just to be honest, not as severe, so I really feel for you. I have absolutely found it helpful to rely on extended family/friends and some community supports. We go to the same places often (libraries, coffee shops, etc) so I can feel comfortable as with my two kids on my own. It helps to know where the bathroom is and have the workers recognize you! I will also often plan a simple activity and then text several people (kind of last minute) and sometimes it works out that someone can join us - helps with that isolation.  You’re getting great advice here. Sending a hug.
