I don't care about school anymore?

I'm 17 & tried studying for my GED. I get frustrated so easy & already ripped up 3 GED books. It's causing me too much grief & sadness so I'm giving up. I'm pretty much a quitter with everything. I don't plan on going to college. I have a learning disability. I'm also on social security. I plan on living off that forever. School isn't an option for me. I will just work at mcdonalds forever. Fck it?! I already broke a tv today too because I didn't understand my math. I'm officially done!
