I am glad they have referred you. For me, I'm also now on a referral, but it took the infection returning 4 months later to trigger it. I also had the antibiotics the first time, and was told it should be a one off.  I can very much empathise with your situation. I keep telling myself that getting worried about what is to come is only borrowing trouble that I'll have to face anyway, but all that seems to do is make me feel guilty on top of feeling anxious.  I wish I tell you something that would reduce your anxiety, but all I can do is try to say, I'm hearing you, and have similar feelings and am in a similar situation - and I hope that helps you feel and you aren't alone.

I have found thinking about the scans themselves to be helpful, talking through a helpline what is likely to happen at the clinic, how long it might take, basically having more of an idea in my head about what is happening next, and focusing on the practicalities of that, which has helped me think a bit less about what the results may be further in the future.  Oh, and planning to purchase my favourite type of cake and sit down and eat it  with a proper brew when I get back from the clinic as a reward to myself for getting through that far. I think on the morning or the night before, to keep me calmer, I'm going to set up the tea pot and cups on a tray ready, keep my thoughts focused on that.
