Rough Nights

Ever since I can remember I've had problems with sleeping. I very rarely ever get a full night sleep, I spend most of the night just laying in bed waiting for sleep to come and when it does it is only for a few hours or I have massive nightmares. This doesn't just affect me, but also my friends and family. Numerous times I've caused a panic to people by texting or calling in my sleep, but there have been times that I've had a good dream and texted my friends "come back to bed huny" and "I'm cold" and they play along and come back and "snuggle" with me just to keep my good dream going. It has gotten to the point that I dread falling asleep because of the nightmares I've been having, because sometimes I can't wake up from them. I've watched people I love be brutally murdered, my pets be skinned alive, even things happening to myself..and all I can do is just watch it happen. If anyone has any advice for me..please tell me..because for now all I can do is remember to breathe
