I have really bad insomnia and I don't know what to do. Do you have any advice?

It's getting really bad and taking a toll on me physically (mentally I'm doing well, thankfully).

I drink so much caffeine to cope but I am guessing that's just messing me up more later.

I take melatonin but I don't think it's working anymore. Benadryl makes me depressed the next day for some reason? CBD doesn't really work. A hot shower doesn't help. I have a weighted blanket 🧩 and weighted eye mask.

I am thinking of doing CBT for insomnia (really strict rules around sleep hygiene) but am scared bc it does involve a bit of sleep deprivation while adjusting (no naps allowed). I haven't been exercising much lately but maybe that will help.

Does anyone have any advice? Or something that will help me fall asleep tonight? :/ 100dc for each real suggestion.

Edit: wtf
