Hi Ashby. I read some of your posts. I've felt like I'm going into some sort of black hole to. At that point do you feel fear coming out of nowhere when the sun goes down? If you have depression,,and racing thoughts when this happens,please tell this to your doctor,and he may be able to transfer you to the right kind of doctor. I'm sorry that you are going through this. I use to have horrible insomnia,and racing thoughts,and panic attacks in that black hole type of feeling. BF
