Hi /sci/, I need your help.

I am currently a brainlet with very little education. I want to do the following:
• Learn All Math, Science, and Programming
• Buld an omniscient AI
• Destroy the entire universe, including earth
• Make sure that nothing can ever come into existence again
• Most importantly make sure that I never exist again

I would just an hero, but I am afraid that my consciousness will come into existence again one day, over and over forever. I want to cease to exist. I want everything and everyone to cease to exist. I want nonexistence. I want nothingness. I want the void. Humans are disgusting and animals aren't much better. Existence is shit. Let's fix it by getting rid of it. Also, if I fail, stop reproducing so the human race can go extinct.

Now please help. I can't sleep. I have to do this. It's become an obsession, but I don't know where to begin.

Also, does anyone else hate the feeling of having a self or being? I feel like I might cut my dick off and then peel off my skin like an orange. I feel so shitty. I am crawling in my skin. Existence is torture. Also i am pretty sure all of this is some sort of incomprehensible illusion or something and I think maybe any knowledge we can acquire is false. Its acataleptic.

Should I go back to the psych hospital? It didn't help much last time and medication makes me feel weird.

Anyway, how do I accomplish this? Before anyone calls me edgy, I literally have diagnosed schizophrenia.
