Hi Nikki,
First we are a support group, we don't bite, we may chew and we do lots of that, but we are a family that generally gets on well. You will get posts about ToS etc, please read and obey them. They explain the basics and the rules.
OK I'm in Australia but came from the UK (Liverpool). I'm also involved in the medical profession. My opinions are mine and are not professional.
One: change your GP. No matter how professional your Mum and GP are it will cause a very difficult working environment, as GID is not acute you have time to look around. Try your local GLTG societies to ask for medics who are TG competent . Look for them on the Net, it's very easy. If your girlfriend is a straight female there is probably little chance of the relationship continuing. If she is a lesbian there is. But if she is a straight female who wants a male partner and children and the whole female dream why should you burden her with your GID. Think hard on this. This is a big decision. You have the right to live your life. You have no right to spoil hers. OK some of us get married in the incredible hope of becoming 'normal' and it only later that we realise we are normal. And we then can ruin someones dreams.
This is not an easy journey. And once you start there are few chance to go back. There is no way of un-telling to the girl friend. There is no way of pretending it was a joke at work. Seek a therapist and discuss it with them. This is a journey many of us have taken. But please do not do it lightly.
Hope it all works out
Cindy
