I have been concerned with my heart for quite some time now and I'm scared I'm going to have a heart attack or something else is wrong with my heart.
I was sitting in my room today on my laptop and out of nowhere I started having some breathing issues. They weren't really severe but I felt like I wasn't able to just breath normally, but I was focusing on my breathing when this happened. And the 2 days ago I was at work when out of nowhere I had a sharp pain literally in one spot of my chest. I could draw a line going down the left side of my body from probably my collarbone, to my lower ribs and it was in the exact same spot on my back - nowhere else.
I want to mention something though, I have very bad eating habits. I will eat fast food, junk food, etc. and hardly any other healthy foods. I did try a Mediterranean Diet a few months ago which was pretty good, but I began having terrible headaches because I completely stopped eating the foods I normally eat. Therefore I stopped eating the healthy food, and went back to eating the unhealthy food. I have worked at a fast food place for about 5 years now and I usually eat there simply because it is convenient.
I went to the doctors about this before and even demanded an ECG be done - which was completely normal (along with normal blood work) and they said that my anxiety was causing this. I have had chest pain/shortness of breath for probably 2 years now. The reason I worry is because I feel like all of the food I've eaten has clogged my arteries for sure and any moment I will have a heart attack.
How long does it take for arteries to become clogged anyway - even with bad eating habits. I'm 20 years old, weigh 136 lbs. and am 5' 10"
