I want to know if anyone is going through anything similar.

I'm so scared of something being missed in tests but then I also have low pain tolerance and doctors haven't been able to properly do medical procedures (rectal exam and abdo ultrasound) on me since I kept getting in so much pain and panicking when they tried. I'm so angry at myself for ruining my chances of getting an early diagnosis if I had something abnormal. 

My symptoms are blood in stools, blood when passing wind, pain when eating, abnormal vaginal bleeding, faecal and urine urgency. Very abnormal for me. I constantly keep thinking of these symptoms and keep thinking the worst for what they could be. I've always been so careful as I was sooo scared of getting ill. I've always had balanced diet, maintain good hygiene, never drink alcohol, never smoke etc
