If you are comfortable with your therapist try getting things out more. If you're not comfortable, maybe it would help to see someone else.

Isolation is the worst. It's really hard when you are hurting so bad and alone. My second year of college was like that. If you can, open up to someone about something. It's really scary, especially if you are afraid of rejection, ashamed, or just afraid. You can pick something not so scary and start there. When someone asks you how you are, you could even just say, "I've been better.", or "I'm upset about the test.", or "I feel lousy." You don't have to explain, but being more open about your mood will help you feel less alone. Most people aren't that shallow, even if they act like they are, but that doesn't mean that it's easy to connect with them, or that they are as sensitive as you are. The good part about feeling deeply about things is that you can experience beautiful things too.

College is "supposed" to be fun, but it can often be very hard and lonely, especially when you are new somewhere. That's normal. Hang in there! What helps me sometimes is getting off campus for dinner, a movie, coffee, cookies, a relaxinI concert or play, etc. It doesn't solve everything, but I get overwhelmed with all the work and being in the same places all the time, and the break helps.
