More or less a year ago I suffered from a very strong depression in which I needed a lot of medication and all that shit, but now that I am cured I am the opposite of a depressive person, I am too selfish and lately I have had enough dreams in which  I die but I haven't had bad thoughts, and I’ve seen some sort of hallucinations (visual) and well there are times when I feel like I hate everyone.

Should I go see a professional?
