Hi, I also am on Adderall and feel like it may be causing me depression. I used to other meds but then was put on adderall around Jan. Since then, I have noticed that I started to become depressed and was diagnosed for it. I am still struggling with my depression but I am starting to think that the adderall is making me worse. Every time I take adderall my depression becomes more severe. Prior to taking adderall, I was not depressed by I am still not sure if its just becaus eof my life events or if it is a side affect. Either way, I feel exactly like you do and I was always a very outgoing person. I still am outgoing but I have to push myself to go out or be with my friends. I also noticed that when the medication's half-life hits me I suddenly become very tired. I have been searching the web but have not found ay clinical studies on Adderall linking to depression.
