FWIW, your baseline anxiety level is way higher than mine. My parents tell me stories of when I was a kid and would come to them with nightmares on a couple funny occasions, but it's been decades since I've had what I'd call a nightmare. I have rational concerns about elements of my future that look negative but over which I have limited control - economic, political, ecological, health, and other general concerns - but I don't fixate on them or dream about them. I relish going to sleep, and have either forgettable dreams or pleasant dreams. I enjoy quiet time with my thoughts, going for a jog or bike ride, or just relaxing in the backyard and daydreaming.

I see others here talking about high anxiety, and I hope that you're able to find a solution for your issues, but your baseline anxiety level sounds like it's orders of magnitude higher than mine. I'm not trying to brag, I just want to share in the hopes of getting some idea of "average person" - am I perhaps far less anxious than "normal"?
