I can relate to some of what you say. Does it get better? I have to say yes. It's important not to lose hope.
I am also an insomniac and it's debilitating WITHOUT any other problems, but combine it with depression it's killer. And I would guess that many of us with anxiety also have insomnia. I know that I can't get my brain to shut off without sleeping pills, which I'm out of. I don't know what your insurance is like, but I can't afford to be introduced to anything that isn't generic. Please do what you can to go back on some sort, if that's what works for you.
I have different issues with my husband, but I know that talking didn't work for me. Odd to some, but I do better with the written word. If I need some hand-holding, I will email him an SOS. I'm able to communicate what I need better, and I suppose it has more impact when he reads it. YMMV.
I too was a degree holding adult (very adult) with a minimum wage in retail. So I can relate. It's so good to make yourself get out of the house, though.
