Help What can I do ?

[LapisLazuli]

I'm extremely stupid. I suffer from multiple mental illnesses, and I am most likely autistic. I have 72 IQ points, and I struggle with every possible task.
I had 8 jobs so far, and I failed in every single one. There never was a moment where my superior was happy with my work.

I have been kicked out of my parents house, and I'm forced to rent a studio apartment, but without a stable job, I am at an extreme risk of being homeless.
I have disability certificate, which allows me to receive some government money, but I'm afraid it might not be enough to live. Currently I'm at mental hospital, and I have told all this to my doctors, and their only suggestion, was to apply to sheltered work for disabled people.
The problem is that it only pays a minimal wage, and it offers no option to increase qualifications and grow.
Is being a janitor and earning a minimal wage really my only option ? I just don't want a life like this.
I have no education (only high school) and I am unable to learn any skills because of learning disability.
Is there anything that I can do to repair myself ? Is there any pill, or brain surgery that could help me ? Make me smarter, faster, and more productive ?
Is there any other option for me, then this, or ctb ?

Look into R/TMS or ECT

Look into R/TMS or ECT

I know about those. I might recieve rtms soon for depression, but I never heard about it making people smarter in any way. As for ECT I know people who had them, and I honestly see, that their cognitive functions are even worse. Googling info about ECT says that it causes memory, and attention problems, and some sources even say, that it can lower your IQ by up to 30 points.
