I think I am suffering from depression or some kind of mental problem for about a year. Sometimes it gets better for few days, but then I feel down again. Few symptoms include- 1. In the worst times, I can't remember anything, not even the simplest things like if I had lunch or not. I suffer from time dilation. for example suddenly I remember that I had a chat with someone but can't figure out if it was few hours ago or few days. 2.Sleeping problem. 3. Breathing problem. 4. headache. 5. others.
