Lost my mask

Lost my social abilities and understandings during covid isolation, while traumatized the whole time by a powertripping roof banger in the upstairs apartment day and night.
I was able to build my mask during Grade School. It served me well all my life. Thought I was just an odd person, able to get along with almost anyone.
Now my apt. block ignores me, my church tolerates my presence, my "minister" can't stand me, those i as in with before can't bebothered with me, my ride to church and back tells me others argue with him that i am a waste of time, my dying last family, my sister, can no longer be bothered with me, my doctor and psychiatrist dislike me.
I haven't one friend to talk w i t h , not just at or from.
I am fighting to stay alive.
I have never in life lived alone before but had to since 2019, and it is driving me crazy. No longer knowing what to say or do with anyone, all consider me weird and useless.
I've never existed like this before in life and,don't want to, but must. How, please, do other unmasked autistics survive, and what should i do to stay sane please!

Thank 💕 you all, xpax
