Your @name of @witsend000 really paints a picture of what you’re feeling right now. I didn’t see your first post regarding the various health symptoms you’re dealing with.

I’d like to reply the post directly over in that group.

After reading your list of health symptoms, I can’t help but think you’re being too hard on yourself! If you don’t feel well, it’s pretty difficult to feel motived to be a mover and shaker during the day. And you’re certainly not useless.
I went through a serious period of depression about 30 years ago. It was debilitating and I can fully appreciate the feeling of uselessness. But in reality, I wasn’t useless, I just never had the sense of accomplishment when I did do something. I was basically going through the motions.

Have you spoken to a therapist at all about depression?
And I’m also going by some of your symptoms from your other post. But have you had your thyroid hormone checked?
One more biggie, have you had your estrogen hormone level checked?
