Up until the end of last year my health has been pretty stable. Rubbish (recently diagnosed life limiting condition) but stable.
Then it all started going haywire towards the end of last year. A positive FIT test meant an urgent two week referral for colonoscopy which was thankfully clear. Covid which thankfully wasn’t too bad. A worsening back problem which culminated in emergency surgery last week and two flare ups of existing conditions.
I think I am struggling with it all, and can’t help catastrophising. For example -
Following my surgery last week I still have pins and needles/numbness in my leg. The surgeon warned me this may be the case as where they were operating wouldn’t affect this. But. In my mind - I’m either going to end up with Cauda Equina again and need more surgery, or lose the blood supply to my leg resulting in amputation 
Another example - I took my prescribed painkillers last night as normal. For the following two hours I felt really out of it, not a feeling I normally get with these. In my rational head I put it down to not eating as much as previous days (bad pain day) and knew that I was taking less than the maximum dose. In my anxiety fuelled state however, I convinced myself I had overdosed and was going to die in my sleep. I know it’s ridiculous but it kept me awake for hours.
I am already on anxiety meds, yet I know this is anxiety based. How do I stop myself from falling further down the health anxiety rabbit hole?
