I quit my job now what ? (22F)

I quit my 8-5 job without setting anything up. The reason was due to my severe panic attacks at work, it became quite obvious to the whole workplace how unstable I am. This was a level entry position. I went to music school at 17 but I quit due to mental health issues. I have no college education, I sleep at my aunts house, no friend’s, never dated , I’m really broke. Today is my last day at work, I feel so burnt out and hopeless. I know I have to keep going and find a new place to work, but honestly I would rather pull the plug on my life than get stuck doing this BS for the next 70 years.
