I can't take deep breaths. It's been like this since Wednesday evening.

First of all calm down. Ive had this for the past 6 months and just now im realizing how to deal with it. Now its gonna be super hard! Heres what you do. When not taking that deep breath your chest is gonna feel super tight and youre going to have the urge to take a deep breath real bad. Resist the urge as hard as you can. You can do it trust me! Breathe in through your nose and just keep doing it for as long as possible. At some point youll take a deep breath naturally and it wont fee as forced. Just keep resisting the urge to forcefully take a deep breath for like a day and i promise you, youll feel like your breathing is going back to normal. It IS anxiety and youre creating anxiety around your breathing at this point which is causing you to create an imbalance of oxygen in your body and having to gasp for more air than you actually need. The fact is you are over breathing and making things worse. So take my advice and just live with that terrible feeling in your chest for about a day or 2 and then youll start feeling ok again. Let me know how it goes!
