i recently just got over constant panic attacks and hypochondria after weeks of bad episodes that sent me to the hospital and have a heart monitor (yk the drill). this was back in march to early april and they said all my tests were fine and even did an echo. i haven’t had any “panic” symptoms lately no dizziness, nervousness, or anything how i felt before or even manifesting fake symptoms except the heart palpitations. they went away for a while esp after my appts and when i’m distracted but i get them every night now? and sometimes throughout the day. my doctor said caffeine could be the culprit as i drink a lot of coke but i can’t shake the feeling of it being something. i know it can’t be because i can be out with my boyfriend for twelve hours and feel completely fine, but if i stay home i get pretty bad. plus ive gotten a few headaches here and there. any  help? :( please.
