The diagnoses of the psych(whatever)ists that i've seen?

I find that they all sound the same. rehearsed. empty. Their advice rings in like something out of a little kids pep talk storybook. The most common thing that was ever told to me is that I need to live my life by what makes me happy and not put myself up to the standards of others. What the hell is that supposed to mean? I mean... duh! I don't know what I want. I haven't know what I want in, well... ever. And I'm getting old and outdated and Im still not sure what I want and the longer I take, the less likely I am to find it. I may never find it. I'm just going to waste my life wandering around searching. While that "life is about the journey" credo might work for some people, it doesn't for me. I'd like to have some kind of idea as to what the hell I'm doing or where i'm going. I'd like to actually have an interest or be able to commit myself enough to something so that I can CARE about it. But I can't. For the life of me the things that at one moment may hold all my interest and attention, eventually become dull and bleh if I stay with it for too long. I can't choose anything... so I have chosen nothing. I don't want nothing.
