I have had anxiety for a while now but just recently I have started having uncontrollable shaking, sweeting, dry mouth, cold fingertips and cold feet. I also have been having difficulty breathing at times and foggy head and light headed. I have been reading about Adrenaline Fatigue, Thyroid issues. I have been to the ER multiple times and they say it's anxiety. They also checked thyroid and it came back normal. I wouldn't wish any of this upon my worst enemy. It's hard trying to work and support a family having these issues almost every other day. Does anyone know or have any idea what this could be? I have tried calling multiple doctors and they don't seem to know what it could be. I just want guidance to get answers.
