Hello, I Am Concerned About My 29 Yr Old Daughter.

Hello, I am concerned about my 29 yr old daughter. She every other week especially recently but for a long period of time gets nauseous, pain in mid lower intestine, sometimes diarrhea which can be stringy if drinking coffee or i forget what else, but has constant sneezing which is very unusual, headaches, no fever at this time. in past has run a very low grade temperature. she does not look good, has anxiety,can't sleep. was in bed last week feeling sick and nauseous.
