its so frustrating be able to feel your heartbeat constantly im really stressing out and sometime i get a THUD in my neck and upper chest , chest fullness , and sometimes pain. im only 18 !!! i did blood test , urine , x ray and everything is completly normal. im pretty sure its my anxiety but the doctors really dont want to prescribe me nothing in case i get " addicted" but i really need it . i fear for my life everyday , stress everday. I NEVER HAVE A GOOD DAY. even weed doesnt help or maybe im not smoking enough. i wake up out my sleep with racing heart. i dont even sleep the same because my heartbeat keeps me up at night. this is ALLLLL DAY. so im pretty surre i have really really bad anxiety
