Hi.... I am sorry you feel crappy. I am sick with the same thing right now, and for me too, it came after a really stressful time. I just found out last week that my stepmother has breast cancer, and I have a one and a half year old sister from her, and it reaaly tested me. Right after I dealt with that news, I got sick.
Take lots of vitamin C, and I always found that lots of tea and good food( garlic especially) is good for when you have a cold. Medication for me is useless because a cold is viral, and there is nothing to treat that, so why bother putting chemicals into your system. Hang in there. Being sick will make anxiety a little worse too. My ears are so clogged, my dizziness is at an all time yuck.
