No problem Hyacinth.
I think lots of us are the same about medical appointments. It comes from not being believed and being treated so dismissively over the years. I am exactly the same, so is my mum. I had no idea I had low-normal blood pressure until I bought my own monitor, because I get white coat hypertension that pushes it up at drs appointments.
We have four main GPs, plus three part timers. Out of those, two I wouldn't agree to see, following bad experiences with both (not just me, other people have had similar experiences) and one you can't get an appointment with to save your life - if you'll excuse the pun.
The head of practice is good, I get on well with him and he's very straight talking, so no head-games to worry about. He has listened to me in the past regarding concerns about my dcs and even though what I was asking was a long-shot, he agreed to test anyway. His bedside manner leaves a lot to be desired sometimes and he can be a bit gruff, but he's a good doctor and I have a lot of respect for him. I don't know why, but my gut reaction is not to go to him with this though. 
The other longest-serving GP is very arrogant, rude and dismissive - doesn't listen etc and I have never had an appointment, either for myself or my dcs, with him that I have come out even feeling ok from, let alone happy with. Dh really dislikes him and he's not someone to take against people at all.
That leaves the two lady GPs, one of whom specialises in paediatrics and has been fantastic with anything to do with ds1, who has ASD, but was very cold and detached when I had to see her for myself. The other is ok, but specialises in mental health issues, which makes me wary, what with the medical profession's tendency to blame my type of symptoms on anxiety, depression or something similar. She was also the one that flagged my medical files with postnatal depression from 12 years ago and delved into my reactive depression dating back 16/17 years and flagged that as well, so both things now appear on every single referral I have made. 
Unfortunately my favourite dr left last year. None of them really appeal for this to be honest. I think asking the registrar GP for a recommendation may be the only way. She may have already discussed my case with someone there, as there was some question about whether my cardio appointment needed to be fast-tracked when they got my first ECG results and she panicked a bit.
