i’m pretty sure concerta gave me heart problems

so i was on concerta for 3 years. i was prescribed between 54mg and 72mg depending on how busy my day was but i would like you guys to consider the fact i was BARELY 90LBS AT THE START OF THIS and only ever lost weight on the concerta because of the non existent appetite. i finally convinced my mom and my doctor that i couldn’t stand this stupid anxiety inducing medication any longer and they FINALLY pulled me off of it. i notice now that my heart beat isn’t well in rhythm its like random as shit 😞 and this genuinely might sound like the silliest thing i’ve ever said but i genuinely believe it fucked up my heart because of how fast ky heart was beating while i was on the medication… just me? anyone else relate or know why?
