Waiting for colonoscopy and scared

Hello all,

I'm 36/female and have been having abdominal pain since February. It started on the left side and it's now on the right one too. I have gone from 66kg to 58kg and my bowel movements changed - more loose and more often. I also have back pain, left hip & groin pain and nerve like pain in my legs.

GP wasnt concerned but has done CBC, CRP and stool sample to check calprotectin level, all came back fine. I then had a CT scan which didn't show anything in the abdomen but revealed a 6mm nodule in my lung which will be re-scanned in 3 months time. I also had MRI of the spine and neck, the results were back pretty quickly but I'm awaiting an appointment to discuss them. I am now also awaiting colonoscopy.

In the meantime I was referred under 2 weeks to a breast clinic as found a lump in my breast. This came back clear fortunately. 

I know everyone has to wait and everyone gets stressed about tests and results but I am feeling very down at the moment.  I have two small children and sometimes I fell so unwell and struggle to look after them and enjoy my time with them. Every doctors appointment was a battle to get any tests done due to my age. So I'm also exhausted mentally.

I know the likelihood of having bowel cancer at my age is low and I was doing ok until that nodule was found on the lung. Now I don't only worry I might have bowel cancer but also that it has already spread. 

Any advice how to deal with this horrible wait and anxiety?

Thanks.
