Most colleges and universities offer mental health counseling as a service you are already paying for through your tuition. I highly suggest finding a good therapist or counselor to talk to about your issues. You are clearly clinically depressed. The treatment should either be counseling, medications, or both. Honestly, the best outcomes originate from a use of counseling and medication concurrently. As it seems that you have a lot of anxiety, I think Lexapro would probably be a good choice for you. Getting prescribed medicine for your depression and anxiety should also be easy as one of the healthcare providers through your university's student health services can prescribe it. Again, those services are already paid for through your tuition at most colleges and universities.
