I think you will find most . people are worked up a few weeks before their follow up tests. I personally have an increase in my stress levels a few weeks before . my routine blood tests( Lymphoma) and at the back of your mind is the  What If question !!!! 

You have made assumptions about you partner - without giving him the chance . 

Also consider asking your GP for a referal to counselling - Loads of research indicate that even after all the treatment etc, some people still need the emotional support 

Hi - most people will be able to recognise and empathise with your anxiety and subsequent behaviour. Your ex obviously isn’t most people - which may be why he’s your ex!

Give your new partner the benefit of the doubt, apologise for your tetchiness and tell him why you think you’re feeling this way and that he isn’t the cause of your stress. 

Meanwhile talk to your GP. Given the state of the NHS it will probably take longer to arrange counselling than is practical for you. The GP may suggest temporary medication to take the edge off your anxiety - something along the lines of propranalol - and to help you sleep.

What you are experiencing is pretty normal given the circumstances - cancer is scary for us all!

Good luck

Thanks for replying. The counselling would take a while to arrange, and of course i got the "do you think you really need it?". Which made me feel i was making a mountain out of a mole hill.
