Hello, Kelly4519, and welcome.

Although you don't ask for assistance, I think it wouldn't hurt to mention just a couple of things that could benefit your condition:

You probably need to have some bloodwork done to determine the chemistry makeup of things for you. That is important not only for the Diabetes but also for the other feelings you have, including inability to sleep normally.

Secondly, you might wish to have a sleep apnea test done through a lung specialist or your personal physician. Lack of one type of sleep called REM sleep could be a major cause of fatigue, low feeling tone, and probably obsessive thinking--I really don't know about that one, however.

I hope you will be better soon and try to get things adjusted so that your feeling tone and sleep return to an acceptable level. They are both important, in my view.

Good wishes.
