The college I attended offered free counseling services to students. I had a session about once a week for a few months and I thought they were very helpful. They didn't prescribe medicine (they weren't doctors, just counselors) and all we did was talk through things and sometimes draw out charts or pictures. It really helped. It felt good just knowing that somebody was on my side, understood me, and didn't judge me. And it put things in perspective. Sometimes you feel like you're all alone, like you're the only one who goes through things or you're the only one who gets bothered by certain situations, but you're not. It also helps to see the other students coming and going from the counselor's office and know you are not the only one with problems and you're not the only one who feels like you can't handle your problems alone.
All that to say, I highly recommend checking to see if your college offers counseling services, and if it does, take advantage of it.
