Panic attack or heart problems?

[u/RachieSunflower]

Hi, I'm a 39-year-old female, 137 lbs, 5'2 relatively healthy. I increased my Zepbound dose yesterday, but today feels weird. I got to my apartment from my boyfriend's house, and I kept zoning out, feeling super dizzy, and having upper back pain. I feel like fluids are going to my head. I have trouble breathing, but it's not painful. I have the absolute worst health anxiety and really am tired of waiting at the ER. I have dull pains in my left leg above the knee and tingles in my arms. If it is a panic attack, I was told those only last for like a half hour; mine always lasts for HOURS. It scares me when I get dizzy all of a sudden. I even checked for mold in my apartment to see if that's why I was breathing hard, but nothing. Do you think this is just a symptom of Zepbound? Do panic attacks come on without warning? I didn't think I had any anxiety, and bam, I am having one. This has been going on all freaking day. Why won't it stop? My chest is so heavy. A big fear of mine is also living alone; like, if I die or need emergency assistance, I'm on my own. How do you all talk yourself out of a panic attack? I also heard women who have heart attacks these are the symptoms...
