Hi NikC14, it sounds like you are really going through it big time.
For starters, I hope you are not shy about calling the Crisis Line. I volunteered there a few years ago, and we often got repeat callers who needed a boost to get through rough spots. I have heard there is now a national number –988– in the USA, anyway. But if you google Crisis Line, you will get through. You may also live where dialing 211 will put you in touch with community resources.
I totally relate to the constant ruminating thoughts. They are an understandable result from not sleeping: your brain can really go haywire. And the thoughts then contribute to future insomnia, a nasty circle. So what to do?
For me, mindfulness and prayer have been the key, the first to slow down and watch the thoughts rather than living them and buying into them; the second for the strength to get through the worst nanoseconds which do not last but seem like they will at the time.
I disagree with people who don’t believe in prayer, though I can understand why they don’t. As for mindfulness, it is sort of a fad right now but has been around for centuries. A couple of free sites: palousemindfulness.com and mindfulnessnorthwest.com
I know when you are really hammered from insomnia it is hard to see the difference between:
1. I’m having the thought that that this is going to last forever, that I should just give up; and
2. This is going to last forever. I am going to give up. —– The difference is huge.
I hope you stay with this site and check out Martin’s materials. The way we think about insomnia can really give it a life of its own, or we can step back and view it more dispassionately, to the point it can lose its grip on us. Not that we can all sleep great every night, but it becomes more of a casual, sometime nuisance rather than a monster.
