Feel like I cant breathe

It's more like I'm just very out of breath. I'm not overweight or anything. I'm perfectly healthy as far as I know, besides getting sick 2-3 times a year. My boyfriend says it's like every day that this happens (we live together and I talk to him about it)and I should see a doctor. It's only maybe 4 times a week. It's a pressure on my chest and stomach and the only thing that helps is constant deep deep breathes and pushing on my stomach. I say it's just anxiety cause I've been dealing with it since I was 12 (which is the earliest I can remember, I'm turning 22 in a few months). He has VERY bad anxiety so I thought he would agree with me, but he still thinks I should see a Dr about it.

What do y'all think?

In 2019 I went to the Dr quite a bit for a few different reasons. I even went to the ER once that year. Every time they'd listen to my heart I was okay so I'm not really concerned. Yes it's a shitty feeling, but I can deal
