Night anxiety

So I have this thing where a lot of nights I can’t sleep bc I get these physical anxiety symptoms . It’s like I don’t breathe right and then my head feels weird . It’s like a pressure and heaviness and it’s uncomfort and so if any fall asleep... anyone else ?

I get this as well. I literally was asleep for an hour and woke up with these exact symptoms and now cannot go back to sleep. I’m trying relaxation techniques and calm breathing but it doesn’t seem to help at all.
