Hi Cas80, I can relate to what you are saying, and I’ll bet a lot of people can.
When the type of fear you describe—I slept great last night, but what about tonight…and the night after that?!—when I find that sort of washing over me, sometimes I freak out a bit, but more and more I just realize that, ‘You know what? I might not sleep well tonight, I hope I do, but if I don’t, I can deal with it.’
I also try to step back and watch my mind, usually via slowing down, listening to background sounds, what I am touching, etc. in other words, whatever it takes to be right here in the present moment. Then I can see the thoughts drifting through. There is a big difference between:
1. “I might not sleep well tonight, the insomnia could come back, I can’t handle this;”
and
2. “I’m having the thought that I might not sleep well tonight, I’m having the thought that the insomnia could back, I’m having the thought that I can’t handle this.”
That might sound silly or simplistic if you skim over it, but if you can slow down, I think you will find it is not.
I dealt with insomnia off and on for many years. I am not saying you will; I had huge emotional trauma in childhood. The reason I bring it up is that I sort of chugged through the many days when I was tired. I would acknowledge it, okay, I’m tired, and just do the best I could. Just trying to ease up on myself a bit on those days. Knowing that actually I cannot totally control ovewhether I sleep well tonight.
Take care, you are not alone in this.
