I don't know if I am Depressed but here it goes.

I often finding myself responding to situations with one umbrella term. "I don't care." Usually what I mean by this is why does my opinion or ideas matter? I'd rather not get into it or involved. Just left alone to be a part of what happens rather than being a catalyst. This often leads to me feeling left out or not connecting with others and rightfully so I guess. Only things I find my self focusing on are getting out of college and seeing where life takes me after that. I have no long term goals other than grad school or starting teaching. I don't really enjoy my time anymore but this doesn't seem to bother me other than the fact I feel bored 90% of the time and thus come off as boring, at least to myself, but people still love me and want to be around me. This just further confuses me. What is going on?
