I am not so sure that a normal life is as you describe it: I live a normal life. A normal boring life. Living in a fog. Probably still unable to attain relationships but I dredge and work. I create a wealth for myself alone. Or try to. Then I slowly age and watch everyone die before me. My parents. My siblings. My pets. I'll die alone.

Real life is far from perfect, but not nearly as bleak as you seem to think. Could you have unrealistic expectations of what normal life is and when it fails to match up you are unreasonably disappointed?
