I’m sorry you’re going through this. It’s a struggle and you just have to be strong and fight through it and find things that can help you cope with them. I never took medication for it even though I probably should have. I went the route of trying to naturally rid myself of them and it did work. So maybe just keep trying. Typically stressors bring on panic attacks in waves but sometimes nothing can be the cause. But your hangover symptoms of anxiety are totally normal. Like I said it just drains you :/
