My anxiety has been getting super bad recently. How do I deal with this?

I have come upon something, anxiety induced, recently ( about half a year ago,) that is really, really affecting me and my daily life and it's really scaring me. When I experience a slight bit of anxiety, I feel like I absolutely cannot breathe. I still can, obviously, but it's SUPER hard to get a full breath in. It's been getting worse and worse and I feel like someday I'm not going to be able to get a proper amount of air.

Nothing exactly triggers this except for any anxiety I get. It could be anxiety about school, relationships, etc. It still feels like I can't breathe every single time. I don't know what's wrong with me. I know what people are going to say. "Just breathe." "Take a deep breath." "Just breathe, in and out." But, I just can't. I just cannot breathe properly. The only thing that gets me back to normal is focusing on something else, or someone else.

For me, anxiety has always been just inside my brain. But now, it's reaching my lungs, and it's freaking me out. Typing this, I can barely get a full breath in. I'm scared. Does anyone else have this issue? Do I need to reach out and get help? I've already tried telling my mom, but she says to just get busy doing something else. Please help!!
