A LOT of medicine is over prescribed Kelyon, and they could be causing you to feel how you are, especially if they keep changing it. Don't lose hope, because you WILL feel better, whether it be through therapy, medication, or time. I know what it's like, I've been there, and so have a lot of people. When you talk to your therapist, be open, spill your guts and don't hold back. If you hold back, they can't help you as well as you might need, don't be afraid.
Don't be afraid to come to me either, I'm always around to talk and I'll drop anything for you.
