Depression problem. A psychologist!

I was in depression since 10 years. I knew this problem around a year when I read a article about depression in newspaper than I realized that I am in depression. In that situation I was hated myself, feeling sad, I didn't like roaming, talking, study, laugh. I went out of the depression six months before individually I never consult any psychologist Now I got my confidence back But I am facing some problems like I don't like chilling out with my friends I can't focus on study I don't like eating, watching movies tv Can't remember many things I like to live alone But I am happy with this I don't feel bad and sadness, I am fully confident I laugh properly I talk to everyone Please tell me Am I in Depression or okay Or I need to consult a psychologist
