Hello I’m in the Exeter area too!
Pop into Neal’s Yard in the city centre (it’s just up from the main post office, opposite debenhams) and have a word with the homeopath in there - he’s fantastic (and his wife works there and is lovely too!) and really helpful. That would be a good place to start.
There are different surgeries depending on where you live but most have a few doctors - I asked to be registered with a paediatrician when I moved here with my daughter 6 years ago and that wasn’t a problem.
Pm me if you’d like any local info (though I can’t guarantee I’ll be any use!!) - it’s lovely to have someone new from this area! Oh and welcome to the board, it’s fantastic
