How is it possible to live now that I've become an adult?

My mother and everyone else don't understand what I have. I have several small achievements, but today my brother wanted me to transfer money to him, but for that I would have to activate something, but at the bank I blocked it so many times that they couldn't confirm my identity, and the worst part was that everyone saw it.
For the first time in months I'm thinking about dying, and I seriously think that would be the best way to deal with everything.
