Hi all...I've been low for the past few days...I have these phases where I feel totally worthless, and feel that my future looks bleak. I'm in grad school, I have no motivation to attend classes. My concentration is low, my grades are average. I took a semester off in between too. I'm not very social so have only a few friends, but those 'friends' it turns out were just blood sucking leaches. I guess I do too much for people with little in return. My relationship with my parents has also deteriorated badly since the start of the year....I feel like I have no one to turn to.
