When I was in college I was diagnosed with ADD. I took medication for it but all it really did was help me stay awake in class -- which in retrospect I probably could have accomplished simply by adjusting my sleep schedule, because staying up until 2 AM and then going to class at 8 AM don't mix!
Interesting, unfortunatly im not into so much anxiety or depression. But hope u will feel bbetter soon. Btw how old are college students? And are all of them ≈ same age?
