Dear Philippa I feel so lonely, so terrible, I just feel like going out sleeping with masses of men. I didn't know you could go down this far. Y Dear Y, I am really sorry. You sound like you are feeling really desperate. Feel free to dump your bad feelings in my direction.
Depression is a very serious condition.
It can be life threatening. Unlike some problems it might not necessarily be healed by time. I don't know what is causing your particular depression or why it started. I do know it is serious and you should take it seriously. Just as I am taking your depression very seriously so should your doctor.
