I have had anxiety on and off for about 6 years, I am 17 years old and this time around I've been really struggling with it. I have been to the ER multiple times and had tests done but everything came back fine. My anxiety doesn't feel normal though, I feel like my stomach is tight, heavy chest, hard to get deep breaths at times, feels like I'm breathing super slow and like my breathing is going to stop, feels like I'm suffocating sometimes, and sometimes my throat feels very dry and like there's a lump sometimes hard to swallow. Is this all really anxiety? I am on Zoloft by the way I have been taking it for almost three weeks. Help does anyone else feel like this????
