I'm sorry you're having such a rough time. You asked if you had depression, and since you're on prozac, a Dr. must think so, also. If the proaz isn't working, tell your psychiatrist or family Dr. There are many AD's out now that are good.
Many times there are physical symptoms with depression. I know you feel like life is passing you by and you want to be back to "normal" and have your g/f with you. That's the hard part. It will happen, but it takes time. You have to learn how your depression effects you, and from that you will learn how to function and feel good. There is so much hope for you. Please Take Care....Silver
