No you are not alone. I get a rush of heat up the side if my face and then something expands like a vein or artery will pop. I also am not yet convinced its anxiety. I know I have generalized anxiety but it doesn't usually feel like I do now. You are not alone though, many people suffer from this illness and I really hope you will find relief. Being around the ones you love and make you happy helps and lots of love and laughter. Stress free things. I wish you all the best. I know how bad it is and in so sorry you are suffering from this horrible illness.
