I have been experiencing anxiety since I was 17 and im 20 now. And recently I have felt like I couldnt breath. I had a pulmonary function test, which was ok and I then felt a little better. But now it started really bad again. I start to feel like I cant breath and then it gets worse and I feel like my test is tight and I am going to suffocate to death. I feel myself to then have anziety. Is this a normal sequence. A weird symptom and then anxiety attack after words. Please help me. It is really scary and bad. I started st johns wort to see if that would help bc I didnt want to start meds again, but I think I might. Any one experience this or have any ideas?? Is it just anxiety or what??
