Hi Flying Fish, I am wondering if you have not had responses because the “headline” of your post says you are not tired, i.e. so what’s the problem.
Anyway, I am sort of guessing that when you say “I’m not tired” you mean “I’m not sleepy.” And that you want to sleep but you are too hyped up, i.e. not tired.
I have never dealt with the challenge of a new baby. So I can only guess that especially with a first baby, that a new mother would worry, and get hyper-vigilant to try to combat anything which might happen, real or perceived.
I can say I know about hyper-vigilance from other causes, and I lived for many years very tired but not sleepy, and yes, it does affect how well you manage (not that you will for many years, I had to deal with severe childhood trauma buried deep, etc etc.).
But it got better for me, so I think it can for you, too. The biggest shift for me was finally learning that my thoughts are what go through my mind whenever they feel like it, and that I do not have to buy into them. I used to think that ‘I am my thoughts.’
Besides therapy because of my situation, I found mindfulness to be a big help. I know it is a fad at present, but it goes back centuries (suggest palousemindfulness.com to see if it speaks to you). And Martin stresses this a lot: cognitive behavior therapy really explores how thoughts and how much we buy into them can affect how we live.
Hang in there, and I am glad you reached out on this site.
