Hi, I'm 6"1, 21 years old, 140 pounds, and have a family history of cronic depression and anxiety. A few years ago I was on citalopram for a good part of a year, it helped with my anxiety and depression quite a bit, but I decided to stop abruptly because I felt it made me feel like a zombie. The only problem now is a year later, I'm back to being depressed and anxious about everything. What should I do?
