weird symptoms

i need to know if this is anxiefy, because im 90% sure its not. ive been obsessed with my heart for MONTHS now, i have all of the symptoms of heart disease. however, i had three ekgs and two echos in february with blood work and chest xray done by two different cardiologist that came back normal. my cardiologist said my heart defect (born with it) shouldn't cause any worries until MAYBE my 60s. i am monitored once or twice a year and have always been normal. i developed anxiety in june of this year, first with the obsession of a brain tumor that sent me into a psychiatric hospital because i was convinced. i got put on remeron and it worked for lime three weeks and then i missed a dose and it stopped working. i started prozac three weeks ago. anyway, today i was running, and idont know if it was because i was thinking about it or if its something serious, but i got a dizzy feeling afterwards. i get this feeling randomly throughout the day, and i also get nausea randomly. im so scared idk what to do, i feel trapped, i feel like im going to die soon, i feel hopeless, i feel like im never going tk get better or be able to live a normal life again. i dont know what to do

i know how you feel i havent felt rite for a whole year now tried so many medd but my symptoms dont go away.
i dont have heart problems just everything else .
i feel your pain

I’ve had this type of anxiety before. It became severe and even had symptoms without there being a presence of anxiety. It started with slight confusion and dizziness, then my entire left body went numb/tight, including my left chest with a sharp pain. This happened several times within a short period and was THEN followed by severe anxiety. I went to the ER each time and everything checked out fine- including EKG, CT, and blood work. My symptoms faded over time but came back after a few months after I stopped taking paxil. My left side of my face would feel tight and slightly numb and I would get a little dizzy. Again had checks done and everything was fine. After accepting the fact it ISNT a heart condition the issue hasn’t come back in over a year.
Now I’m having fibromyalgia symptoms I’m trying to get through. It never ends with health anxiety and our minds are creative in causing craaaazy symptoms in the process.
I’ll say a prayer for your comfort in this process. Talk to your doctor about other potential medicine you can take. Sometimes people aren’t effected much by certain medicines.
