How about aim for making a wish and fufilling it. Even if it's learn how to make a pizza from scratch. I read through your points and have a few questions, Do you feel that others find you untrustworthy, or have they stated this to you? I often feel I'm too strange to really get along with my peers. As for your attitude on sex, I don't feel it's wrong.. but I'm female and I know guys can have this machesmo attitude towards it. (believe it or not females can too). As for family make your own! They say you can't choose your family I say bipcus! I did, and it works just fine.
So yes.. find a new purpose and fufull it. Make it as trivial sounding as possible and do it! Remember, you have to make you happy.
