Welcome.

Good luck with your sleep study. A lot of people who get diagnosed and get a CPAP machine do really well if they get adjusted to it.

Well it sounds like you did a lot better with your former employer, so, well, in my opinion you seem to want to keep a job, but you need some accomodation at this new place. Or to find a place that is more like your previous one. I know you said you want to quit but it just seemed like you would feel better about yourself if you kept a job, just as long as you weren't completely tired all the rest of the time. Just my opinion based on what I read.

Disability is probably an option but takes a while to and a lot of effort to fight, they try to deny it. And probably doesn't pay that much.

I can understand the feeling of confusion and frustration... I feel that way regarding choices with how to spend my time and energy versus the need to have more income.
