Health Anxiety becoming entirely overwhelming...

[ms639]

I am a 33 year old Male with a good job, solid family life and am healthy (no pre-exsiting medical conditions, eat well and exercise regulalry)

Just recently however my life has been flipped upside down by health anxiety. I have recently returned from South Africa from a holiday and had an upset stomach (this was 4 weeks ago), I have subsequently come down with severe health anxiety, convincing myself that I have some kind of cancer (stomach, bowel, pancreas etc etc).

I have had 3 GP appointments in 4 weeks but I cannot break the cycle that it is something really serious, I am stuck in this vicious cycle and it is consuming my whole life, it's the first thing I think about when I wake up and my brain is living in my stomach right now.

Any tiny twinge I get absolutely fixated on, it's stopping me from eating as normal or partaking in day to day activity, I just want to sleep to try and be unaware of what's going on.

This is entirely new to me having had little to no anxiety in the past. If anybody has any advice it would be hugely appreciated
