Welcome, LeeAdam,
It's a difficult situation to be in, but as you are well aware, suppressing it won't work, and you will need to take action of some kind to allow yourself to be free. This is a matter of your human right to be the person you feel you are.
I strongly endorse the suggestion that you seek counselling from an experienced gender therapist. They will be able to help you with finding a way forward, and you must find a way forward as is very clear. Only talking it out with a gender therapist will help you move forward because the issues that need to be resolved are intertwined with many people, above all you.
I too first discussed my long held secret with a psychologist, and I can tell you that it was the best thing I have ever done.
I look forward to see you grow into whatever path you decided to take. The journey will be rocky, but the destination will be worth it.
Take courage, it gets better
