I feel the same way, as soon as I have a good moment I get my hopes up and then when I fall again it is feels that much worse. Today I woke up feeling calm and just wonder how long it will last. My husband keeps asking me if I have PMS or am pregnant because I have such extreme ups and downs (not bipolar just radical mood swings) because he just can't understand my Depression--of course we don't really understand it either. I used to think I should not enjoy the good moments because they won't last long anyway, but today I am trying to appreciate the relief of feeling ok. Hang in there, you are not alone. J
