I haven't been diagnosed with depression or anything but I have other issues that cause me to go to therapy and I honestly think that you should try to get in with the therapist at your school. It feels so good to have someone to tell things to who don't judge and who have no emotional investment in you. Just try one session, and then you can decide if you want to go on an anti-depressant. I am at that point right now where I need to decide if trying an antidepressant is good for me or not.
