Health problems or anxiety

[Trina2413]

A couple months ago after getting dental work done I started feeling very run down. I though I had strep but test came back negative but positive for thrush. Took thr medicine they gave me but ever since then I have felt so ill. I have allergy type symptoms awful red throat and sometimes cough up green mucus. I have lost 14 pounds in 2 months and wake up every morning with pounding heart and constant dry mouth and feeling of dehydration no matter how much water I drink. I have noticed increaded spider veins on my legs, thighs, ribs, and one on stomach. However I can't stop stressing about my health. I have had Cbc, Ana, Tb test, thyroid test, carcinoid tumor test, chest x ray, stomach x ray, hormone levels, and Hiv, hepatitis C and B tests and all come back negative. My boyfriend is telling me that it is stress and anxiety. I am just stressed because Dr say thrush is unusal in my age. However, I read that smoking, diets high in refined sugars, and dry mouth can also cause this. I can no longer determine whether there is an underlying health problem or if I am making myself sick with stress and anxiety. The only thing they found was in was backed up to my colon from constipation. I am still not going regularly but trying. I am afraid I have a ragging fungal or bacterial infection in my body or blood or am terrified that I have some kind of cancer. Is all my worry and stress making me sick? I have suffered from anxiety most of my life, but don't even feel stressed anymore. I'm wondering if I have run myself down with stress and worry. Any comments or suggestions greatly appreciated
