Hi Doctor I Currently Have Been Experiencing Some Stomach Issues.

Hi Doctor I currently have been experiencing some stomach issues. On and off for the last 6 months I have episodes of extreme abdominal pain and can't keep anything down. All i do is throw up constant bile. I can hardly eat as well and my muscles are starting to feel extremely weak. What should I do? I dont have another gastrologist appt until March 29 and my family physician is rude and never gives me a clear answer nor ever gets back to me with test results
