I am a twenty-year male who is diagnosed with MDD “major depressive disorder”. I take Cipralex, 20 mg daily at bedtime. I eliminate negative ideas very well and swim daily. After swimming, I feel high, positive. I remember, two days ago, I felt something unusual after swimming; I was totally positively charged!! I felt that I am a great man who the mankind does need him! I felt that without my existence, the world would be worse! Very great moments for a depressed! As a result, I spend 4 hours exercising to lengthen such moments!! The problem is that once I sleep and then wake up, I become other person. I have to recharge myself positively again. After waking up, I feel a great desire to oversleep! If I do wake up, I feel headache, loss of joys and so on. This also leads me to spend more hours in the gym because I know it is difficult to me to get up and go there!! My question is how to maintain the positive side of me for longer? I badly need help!
