[Dr. Kokil Mathur]

Hi
Welcome to the MedHelp forum!
Abdominal pain, nausea, gas, diarrhea, joint pain and fatigue can be due to Crohn's, IBS, ulcerative colitis or celiac disease.
Pancreatic enzyme disorders, liver dysfunction, HIV, cancer of the gut, and infections by parasites (giardiasis, amoebiasis) can all cause persisting diarrhea. Lyme and lupus are other possibilities that present this way. Please discuss this with your doctor (GI doctor).
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral.
Take care!

Do you have sleep apnea? It causes some of the symptoms you mention.    Madlyn

This really sounds like anxiety.  Anxiety can cause all of the symptoms that you have at this point.  My advice is to go to your doctor so that they can do testing on you to rule out any physical ailments. If all is okay with you physically, then you should see a psychologist and talk about what is stressing you out.   Goodluck
