I think I may relate to your post. I've been having that feeling, and it seems to increasingly becoming worse.
I will be seeing my pdoc next week, so I will take this scarey feeling, up with him.
It really sucks, and it can be scarey. I also keep focusing, and I do not want to, on what lies ahead in my 3D world, and it is making me more melancholy and I'm sure it is a main reason behind my super,chronic fatigue problem,which is worsening rapidly.
Just waking up,moving my eyes and feet,exhausts me enough to just lie down and fall asleep again.
Why can't I feel that fatigued enough to fall asleep in the PM?? The PM time before bed, my mind races with the horrible thoughts of those I loved that have passed on.
Pdoc's pills may help, but just can't clear or wipe up the ugly,sad,memories that are driving my insomnia.
I've rambled again, MP,you must know me by now,eh?
I apologize,and have no answer to your post,but can so strongly feel where you are coming from.
Please take care,
DE
