I'm so sorry you've had to go through all this. But you are defiantly not alone. I also feel like I'm loosing my mind also but with a voice attached. And also dealing with PTSD, which you might be dealing with.
Please take care of yourself. Don't be afraid to take that first step into asking for help. You may be surprised what will happen..
Stay strong and don't be afraid. We are all here to help and support you on a path to recovery, all you have to do is take that first step and seek help.

Best of wishes, huggs.
