Hi Faye -welcome to the forum.
I would think that if your gynae recommended either the pill or a low dose HRT then this is what you need. It's not right that you should suffer like this when either of these two things might make all the difference to you.
Go back to your GP and ask for a prescription. At your young age HRT does not seem to present the same risks as it does for women over 50 and you might very well get your life back!! HRT will also give protection to your heart and bones up to the usual meno age of around 51.
Let us know how you get on. There is lots of information, advice and friendship here.
