Do I have depression or just mental?

For the past 2 weeks iv gotten little sleep like 3 hours a night. I smoked weed 1 time in 2006 an I think it was a bad trip, but iv been fine up till now. Ic been having anexity attacks cause I remembered that night when I did it. Now iv been sleeping 11-14 hours everyday and still tired. I don't care what's going on like when you get waken up. I haven't ran or worked out in 4 months and been eating unhealthy and consumed alot of sugar. I do have ADHD but haven't taken it since 2009. Can someone give me a possible answer? Thank you!
