I wish I had the answer. Are you on any kind of meds for anxiety? Sometimes they can help when nothing else can. It sounds like you are doing everything you can do. All I can say is keep doing wht you've been doing.

Your not alone, I promise. I feel the same way.

Just try not to give up

Wish I had an answer... I have the same problem at times. It's not a fun place to be..

Number 1- have a safety plan made up and make at least 1 other person aware of your plan. ( Just in case of an emergency 🚨) then take a bath, call a friend, this one will make you cringe ( sorry but it works) try classical or piano music ( how boring, right? But sometimess it soothes a soul enough that it will calm your mind.) jump on here and vent- ask questions- here is a HUGE one- help a friend or 1 of us from this site.... when you are helping someone else it makes you feel a little better cuz some of the pressures are off yourself for a brief minute!!
Hug a pet!! ( even if it's not yours, you might ask first- people get kinda protective!! Lol
Hope you found truth and humor in my answer- I am in a pretty decent calm mood right now, Thank You God! 💫
