Why do I think like this?

I think you are just too smart for your own good. Sounds to me like no one will ever be as smart as you and you will have to go through life as a loser and a loner. It's a shame that you aren't smart enough to recognize the fact that your behavior isn't bringing you any permanent happiness. If you were really as smart as you think you are, you would be on a determined path to turn yourself around. Also, you state that you are "good with psychology". My friend you are controlled by your own psychology which is seriously in need of some professional intervention.
