Okay So I Smoked Meth A Couple Times With This

Okay so I smoked meth a couple times with this guy about 2 + weeks ago and shortly after I partook in smoking it I started feeling tightness in my chest, shortness of breath and difficulty taking a deep breath. I tried using my nephews inhaler to open up my air way but it doesn't help much. I got so paranoid about it a week ago I rushed myself to the hospital (failing to tell them about smoking the meth) where they did a x ray on my lungs which came back normal. I have a apt tomorrow to go see my doctor but I suffer from anxiety and am very anxious right now. Should I go back to the emergency room?
