Hey there! 20-year-old white female here, 5'3", been obese and struggling with my weight all my life (I'm around 220 lbs last time I checked about a week ago), but otherwise not many health problems except I frequently get upper respiratory infections and colds. About a year ago around this time I experienced my first, what I and everyone else assume to be, panic attack, along with random abdominal issues. Since then I've been to the hospital three times in 2014 and my GP a few times. I've had about 6 or 7 EKGs and they've all come up as "abnormal", but each time the doctors didn't seem too worried about it and figure maybe it's my normal heartbeat. My first hospital visit I had a CAT scan done for my stomach and not much came up but traces of a stomach virus, and I was left to stay overnight for observation. I had a few chest x-rays done and an ultrasound of my heart, and they didn't really tell me if they saw anything or not so I assume there wasn't anything bad.
Anyway, the second time I went to the hospital, they straight up told me it was a severe panic attack. My heart rate was near 150 I believe, my bp was high, and I started to go numb around the mouth and fingers from hypervenilating so much I almost thought I'd pass out in the ER. This visit was at around 1 am, the time of night my symptoms usually occur. I either am up (I stay up late and generally have always had trouble sleeping) or am woken up by feelings of intense panic. I experience intense palpitations, hot/cold tingly feelings, chest and left arm pain, hot flashes, shortness of breath, lightheadedness, and a whole host of other symptoms. Sometimes I also feel I have an urgency to have a bowel movement. I go multiple times and get chills that accompany it, but it's always normal and never diarrhea.
My third hospital visit they did multiple tests and pretty much determined yeah, I have bad anxiety. I forgot to mention along with the EKGs they've done multiple cardiac enzyme tests and they all were fine, also. Anyway, I was given a two week supply of 10mg of Lexapro, one a day, and a 8 pill bottle of .25mg Xanax as needed for when I feel an attack occur. Thankfully I got accepted for Medicaid so my medications are covered, so I went to the doctor and I've been taking the Lexapro every day (only missed about three days total) since around September. For the first few months I felt great, super happy even and seemed to have lost some weight though I think I'm gaining it back. Right now I do still think it's working, makes me more balanced, but I do still occasionally experience a panic attack and while I've been told that's normal, I think I might want to up my dose.
Before taking the Lexapro I lived every day in constant fear I was going to have a heart attack, and while that feeling has lessened it still gets me sometimes. There is some family heart disease (my uncle, still alive, had a heart attack around his mid-thirties, my grandma has a-fib and has had three strokes, and just had a pacemaker put in, and my granddad on my mom's side had a quintuple bypass) and most of my dad's side of the family has diabetes, including him.
I know this is long-winded and kind of directionless, but basically I wanna ask; should I be worried about my heart, even though multiple tests proved me wrong? Is it just my anxiety ripping me apart?
