New mum and so anxious

I recently noticed blood in my stools which was accompanied by a number of other things change in bowel movements, stomach cramps and I’m also extremely exhausted! I did put this down to having 10 month old son and running around after him. Anyway I went to the doctors and they did numerous tests and discovered that I’m severely anemic my blood tests came back abnormal and my FIT test was positive so I got a 2 week referral to the cancer team and I’ve got a capsule colon colonoscopy tomorrow absolutely terrified of what the results are going to be I have 3 young children to take care of and my anxiety is through the roof! Is anyone going through anything similar?
