Panic or anxiety attack

So I’ve always known I’ve had anxiety but I’ve never gone to the doctors about this as i didn’t see it as a big issue. Well recently I feel like I’ve been having some sort of panic attack.

Usually if my anxiety is bad, I hate even listening to music with earphones in when I’m in public because I think everyone can hear it or they’re judging me and I have to turn it all off to calm down. But recently, twice the past two weeks, my body would start to shake uncontrollably for a few minutes until I can catch my breath.

I’ve been getting chest pains on and off for almost a year but my doctor said it was from low iron. It felt like my heart would skip a beat at that time. I’ve been taking my tablets since and haven’t had a problem until recently, my chest pains have come back. This time it seems to be coming more often and almost like a sharp stabbing pain.

Usually this would all happen at once if I’m arguing with my boyfriend and I’ll have the thought of him leaving me or doing something disloyal because of it. He tells me it’s all In my head and I should start thinking positively because he’ll never do that. But thinking positive doesn’t always work and the thoughts get in the way of the relationship. I know this is probably something I should go to the doctors about now, but how do you go about it with them? The thought of having to tell the doctors makes me feel anxious, I wouldn’t know how to do it without feeling like it.

The only person I’ve told anything about this to is my boyfriend, even then I feel like a burden and like it’s not really a good enough reason to get help. I know Deep down I should but actually going to get help seems a bit scary. The doctors in the uk are different, they’re very unbothered. Well the ones from my gp are anyway.
