Same thing happened to me. A few months of stoned introspection and I found my grades better than ever, social life was booming, and i was overall just a happier person.

Weed (and especially LSD) opens you up to critical analysis of yourself, which can be a scary thing at first, but you'll find its all for the best after a while.
