And this is why...

And this is why I don't think it's anxiety.. I don't feel good for a while then I feel fine for a couple weeks/months then go right back to feeling sick!!

I think it's difficult to distinguish the two...symptoms caused by physical problems...and those caused by anxiety. In my case, physical problems...an infection, hormone imbalance, stomach flu etc...all cause anxiety. Severe anxiety on the other hand can affect my immune system and make me more vulnerable to diseases.

Did you consult your doctor when you were 'feeling sick'?

Diet is also something you may want to look into. I am not well when I am not eating enough vegetables.  I feel sick when I am constipated for a few days (sorry lol). I feel depressed and sick. Diet is very important. Processed food, preservatives, unhealthy junk food, bad food combinations can also affect the way you feel. You become what you eat and drink.  Too much caffeine, sugar, alcohol and nicotine can also trigger anxiety.
