Constant feeling of dread…help

Im actually tired of this shit my physical anxiety symptoms are so draining like why tf is my fight or flight switch constantly on. I don’t understand why my body doesn’t want to catch a break surely like when is it enough? the constant chest pain. palpitations and derealisation. It’s like my mind and body is separate and my physical anxiety has a mind of its own…is it too much to ask to wanna feel safe in own body fuckkkkk…
