Go to your counseling center today. Make an appointment and go. You will hopefully get some insight as to what might be going on and steps you can take to feel better about your situation. Feeling good about yourself is more important than anything else.
Not everyone makes friends in college. I didn’t make one single friend while I attended college. I had friends, but they were all through work and that’s who I socialized with. I didn’t let it bother me. I wanted a degree, and to me, college was my “job.” Not everyone who goes to college is going to have the best four years of their life, and that’s ok. The best years of your life are yet to come. That has certainly been true for me and many other people.
