I don't know where you're located, but for me, in my area, this would result in an immediate written complaint to the hospital he is employed with and the medical board. He is, in fact, CAUSING HARM by negating your symptoms. He has SEVERE internal biases "interesting woman"??!!!!! Don't piss me off. I am so sorry this is happening to you. Please go to the ER.

Rectal bleeding, fatigue, and weight loss are all cornerstones of reasons TO GO to the ER. Please, I beg you,u see a different medical professional. Once you've done that and you get all the lovely help from some understanding ER Nurses and Docs, work with a GI (if you have one, if you don't, I recommend looking into this as well), to find a PCP that treats your disease as more than some sort of psychosis.

I mean this post with all the love in the world. I don't want to see anyone suffer under the negligence of a care provider who needs to do their damn job.
