depression has gotten unbearable

Of course embarassing moments (in all their shapes) suck, especially if you think back to them after some time and especially if they were as bad as yours. But we have to learn to live with our mistakes. I don’t know how you are feeling apart from that experience but it seems like you are better off than many people on this forum (correct me of I’m wrong). It is now important not to fall into depression because otherwise you will actually end up truly considering suicide.

Moving away from one’s family and friends is a hard step in everyone’s life (I haven’t recovered from it yet). It is important to find the right friends at university as fast as possible (there are always meetings and events to bring people together). Many new students will probably feel similar with what you are going through. Don’t hang around the wrong people, or for that matter no one at all. Whether you will remember your life at university as happy and cheerful will strongly be influenced about what you do in the next few months – being depressed surely doesn’t help you.
