Good luck on the pills (incidentally, which are you on?) and I'm sorry that it had to go this road. However, if they are the right ones (and it may take a while to sort them), then they will help.
At least work is one less stress for you- and when you feel well enough to cope, you can move out of home, and your life will start to pull back together. So, take baby steps. Slowly but surely, you can get there.

I'm sorry that you broke up with Cameron- he seemed really good for you. Maybe you will get back together once you're back to your usual self. But if you don't, then there are lots more (wo)men who'll love you.
