To be feeling sorry for myself and struggling to keep it together

[JustMeAndMyTins]

I know this probably belongs in 'health' but I am at the end of my tether here and I keep seeing comments about AIBU getting more traffic so here we are.

I've not been a good sleeper for a long time but - although it always made me feel crappy -I could nap for 2 or 3 hours if ever it all caught up with me.

At the beginning of covid I was really anxious and my sleep worsened and I, strangely (because anxiety is not new to me), lost the ability to nap! Long story short, I am no longer anxious about covid - but I've started to get anxious as a byproduct of the sleep situation (rather than as a cause of it) - but my sleep is getting worse (one hour last night) and I still haven't regained the ability to nap. Aside from feeling dreadful, I've started getting terrible headaches. And now I'm getting pins and needles in my limbs - mostly my left arm and hand, sometimes the right joins in and today my feet are doing it sporadically too. Any idea what that's about?

I've got a few physical health problems (IC, GERD, oesophageal spasms) and the sleep deprivation on top is now crippling me. The doc has given me some zopiclone who is great but not a long term solution (and apparently is terrible for reflux so that might explain the awful pain I've started to get in my chest) but is fixated on every symptom being anxiety. And as I said, I'm very au fait with anxiety and this all feels different.

Please tell me of your insomnia cures. At this point, I've gotten to a point where I worry that I'll never be able to fall asleep again unassisted. I'm doing guided stuff, have a white noise machine, have stopped drinking coffee later in the day, I exercise...

I'm doing a terrible job on my worst days - and none of us can afford to let that happen in these uncertain times. I'm crying off and on all day with sheer frustration at how exhausted I am. And I have quite a relatively senior corporate HR job where I need to be useful.

I can't go on like this. But I hate that I'm feeling sorry for myself when people are having such a hard time. Any words of wisdom?

I didn’t realise I’d added a poll. I wonder whether the 17% who said I’m being reasonable have ever suffered with insomnia, anxiety or migraines...

Op. apparently there is a link between Gerd and sleep apnea. I was waking up tired and with headaches, even after ‘good nights’ sleep.
Apparently the acid accumulates in back of your throat and your body keeps waking you up to stop you choking, not necessarily fully, but enough to deprive you of deep sleep, which will leave you feeling tired the next day.
I have found the only way to deal with gerd is through cutting out carbs and sugar. Tablets made me feel worse and gave me terrible anxiety. Maybe thats worth exploring.

Thanks @squirrelsbizaar for the suggestions. I definitely don’t have apnea because I did one of those sleep studies in February but I think I need to take a look at my diet for my overall health (I’m not sure it’ll help my sleep though). I cut out sugar for years and I do think my GERD might have been better at that time. I need carbs though. Different bodies and all that. I reckon I need a bit of a habit and lifestyle overhaul...
