I'm sorry you're having a hard time. Have you discussed this with your pdoc? I was on Epilim and didn't find it very effective for me. I was on an anti-dep at one stage called Edronax, and it definitely helped with the energy levels.
I'm now on Lamictin as a mood stabiliser and find I'm losing weight (I cannot say for definite that it is because of the Lamictin)

It is terrible to feel like your body is no longer your own, but please understand you don't need to live like this. You just need the right meds prescribed.
