Medications vary by person. I've seen ex-friends of mine completely change as people when they're on meds. Some were more functional on meds, and some felt worse on meds.

I've been on over 40 different types of medications, and none have worked for me. They all make me feel depressed, anxious, or both. Other meds like Celexa made me feel suicidal. I started taking meds at age 30, so I was fully developed by then.

Since you've been taking meds while you were still developing, I would imagine your brain chemistry has been affected by the longevity of medication use.
