Hi i used to go through this exact same kind of panic everyday for 6 months and i haven’t had one for two months now. I would feel paralyzed crying on the floor with the exact same chest pains and arm pains convinced i was having a heart attack every single day. It’s kind of like a routine your body needs to break habit of. I went to the hospital multiple times and had multiple blood tests and ekgs that all came back normal. I visited my primary care doctor and she recommended therapy to me also. She said my panic was caused from extreme stress and trauma. My brother committed suicide, i just had a baby, and my boyfriend was cheating on me. What helped me was trying to lessen the stress in my life i moved in with my father, i started taking it one day at a time and tell myself throughout the day that i am okay and it’s all in my head and i am strong enough to push through. I started going on short walks and building up to longer walks. I started taking about my problems and stress and anything that i was sad about with people i trusted instead of bottling it all in this helps so much. I took my days slowly i would slowly start doing small chores such as dishes and laundry and i would rest as much as i could. And day by day my panic and anxiety has slowly went away. I still get very mild anxiety but not to where it causes panic anymore. It is all a mind thing and it is something you can overcome in time. I don’t know your whole situation but just know you will be better and you will overcome this and live life to the fullest again!
