Honey, I dearly hope that you get better, but as for now, I think you just need some good advice and someone that you can trust to talk to. It's okay to feel sad sometimes, because that is a natural human emotion, but if you are dealing with a long term depression here, then I really think you should talk to someone. Maybe a counselor, or a therapist, or maybe even a psychologist. These people are trained to help others out. Making friends can be hard, Lord knows I've tried several times. But before you make some friends, I really do think that you need to help make yourself happy. Do you have at least one friend? If so, then put forth a lot of effort into that relationship. I'm sending positive vibes your way, my friend.
