My advice is to get help — to find a good therapist and figure out what works for you.
For me: I take medication daily and have for many years. I also try to exercise a lot, because there’s some evidence that exercise lessens the symptoms of anxiety, and I try to use the strategies that I’ve learned in cognitive behavioral therapy to cope with my illness. But it’s a chronic illness and it hasn’t, like, gone into remission or anything for me. It’s something I live with, something that I’ve integrated into my life. And we all have to integrate stuff into our lives, whether it’s mental illness or physical disability or whatever.
There is hope. There is treatment. You are not alone, and while I know the struggle feels at times completely hopeless and futile, there is a far shore for the vast majority of people, and I wish you the best.
