My wife had a mental health crisis last year where she could pretty much only scream and cry. For about 6 months, her life was only screaming and crying. She couldn't sleep. She couldn't eat. I mean, she ate, but it often involved gagging and forcing food down. At her worst, she went three whole days without sleep. We took her to the ER, and they basically just gave her Xanax and anti nausea medication to help her eat, then sent her home. Xanax helped in the moment but made everything 10x worse in the long run.

After several months, we finally got an appointment with a psychiatrist and started trying different medications. It was a long and painful process to find the right one, and we had to change psychiatrists once because of laws in our area preventing online psychiatrists from prescribing certain medications. But we eventually found a psychiatrist and combination of medications that works for her. It took a few months of being on it for it to really start helping. But she's doing very well. She started working again recently. She can run errands on her own. She can be left at home by herself.

My answer is: see a psychiatrist.
