I think Litha_26 is right, also you need to start now at trusting what your Dr. says , also remember that when we self Dx ourselves we are only getting a fools answer (not to sound mean, just reminding you. Don't 2nd guess what your Dr. says, also why rack up bills if your not going to trust answers, it may seem hard to realize that you may just have mild anxiety, we all want to pinpoint it to other things (makes it easier) try to ask yourself whats going on, write what you feel see what comes out. good luck on your blood work!
I wake up almost every night sweating. Are you on any anti depressants? My sweating all started when I started taking Lexapro. It's all around my chest and neck area. It also causes really strange dreams. I went through a period when I thought I had type 2 Diabetes. I'm now at the age my mom was when she found out she had it. As for the weight, have you been doing more outside seasonal work? My husband lost 9 lbs. in a month since he started cutting the grass.
HA really bites. I've had it for almost 8 years now and I can't even count the diseases I though I've had. Oh and I just remembered I used to wake up having panic attacks. I would wake up covered in sweat from them. I wish you the best of luck with you blood work.
