Liv.... have you ever tried non-medical stuff to help? There are so many small things you can do to help you. I've recently joined the gym... I hate going there, but I force myself, I got a trainer so I have to go and I feel loads better afterwards. I use a lot of vitamins, sit in the sun for 10min a day, don't listen to sad music, but try upbeat stuff and sing along whenever you can. If you can't join a gym, go for a walk/run or do sit ups infront of the TV... Don't watch sad movies etc. These can help a little...
