Am I Suffering a Kind of Psychological Problem?

I'm a 22 year old girl. Fo a while, I'm going so crazy... I really don't like talking to family. I prefer my computer, not even studying...I've lost any reason to do anything, even studying...I'm going to be graduated in 5 months. I am having bad dreams ....and not really enjoy being with my boyfriend or our talks... I'm usually not in a good mood, except some times if I'm in the university or in a class teaching kids. The rest of the time I'm like a dead person . What should iIdo really?
