So it's probably all in my head but my chest has been tight. And I feel like I have to take deep breaths and when I do I feel like my brain is affected? I've had tightness of chest before but I don't know if I'm more stressed out about things that it goes away and comes back. Anyone get this? I get it one after another... it makes me think something is getting worse and it's super scary!!!!! I don't know what to do. I feel like every air is limited. =* or that something is very wrong.
