I miss my life too, there is a chance that you'll move on from this and be just fine and happy and "normal" again. However, depression has changed me forever (I think a lot of other people would say that too), so whatever I move onto won't be the same as before. I think I have over-idealised my "normal" life, so from where I am in the pits of depression it seems unattainable.

I remember when I was in my 20s and the depressions started to lift there were some very exciting times as I started to live again and I felt that I had to cram in more to compensate for the down time. I hope that you will have some better times soon.
