I went through a lot of stuff a few years ago, and know exactly how you feel. Like nothing matters. What helped me, was when I got off the meds! I told myself that I wasn't going to continue living miserable. I had my ups and downs throughout the way, but I was determined. What really helped me get out of it was when I started seeing a difference in myself. I was proud of myself. And that fueled the fire to help me get even better. The more I accomplished, the better I felt and then the more I accomplished! It was the opposite of a "vicious" cycle!
The meds seemed to either make me sick, or make me a zombie. Prozac made me break out in horendous hives. Once all the meds were gone, I was able to think clearly and figure out what I wanted.
And what I wanted was to control my own life. Just like you, someone else stole a lot of MY life away from me, and I wasn't going to let them take any more!! You can do it, you are so much stronger than you realize!!
