Medications help alot, they allow you a chance to get some kinda control over what you have.
After that, its all on you to repair the damages you have caused. DOnt think of it in a bad way, but in a chance to make right things that have gone wrong. Even if you try and arnt successful, you will be much farther along than if you never tried at all.
And be open with your therpast, if they know whats really going on they can really help you help yourself. In this case you really get out of it what you put into it.
Good luck Bill
