Is college an answer?

I was an over acheiver in highschool I have dotted every "i" and crossed every "t". I have gone through hell (worse) to do so, and it almost cost me my life (overworked by highschool). Knowing this I took comunity college and failed misrirably at it. (take me 10 hours per ignment, however it was easier than highschool which I had way too many ignments in one night).I have never taken the full SAT (took psat 4 times and did very horrible everytime, so why waste money) I have ADHD and dyslexia and it takes me hours beyond hours more time to finish what the average person does. Half of the bad habbits I have picked up (drinking,meds for stress,smoking) all were the product of my stress in highschool. My best friends want me to apply at a college they are going to. Should I apply? I dont wana be working low budget jobs all my life, but I feel if I get that same stress again I may even retort violently( in highschool I resorted to suicide as a solution for being less than perfect)
