Hello Ida,
And a BIG Aussie welcome to Susan's. You are most welcome here and are quite safe. You are among many genuine and thoughtful friends. Feel free to ask any type of question, they are all important. The only silly question is the one you never ask.
I too came from a Catholic background, and can understand your parents viewpoint, albeit being totally inappropriate. But nevertheless. Yes; a good move to leave to a more appropriate and positive environment would do you the world of good.
Transitioning is a complex and involved process, and may take you sometime to see its fruition. Typically speaking a minimum of 2 years would be the absolute minimum time frame you should allow for.
I'm so sorry to hear of your girlfriend. That appear to have been a tragic loss for you. As you are still counting the days, I suspect you are still grieving for her. This is very natural and grief too, takes its toll and time to move through. If you are not aware of the various stages of grief, I suggest you ask your therapist, so you can chart your way through those issues before you take on the issues of transitioning; which by their own virtue have their own unique set of circumstances to overcome.
There are some considerable hurdles you have to jump in the transition "stakes" and I'm not sure how familiar you are with them. Might be a good idea if you come up to speed with those before anything else. So; the floor is yours, just ask away.
In the meantime, I hope you enjoy your stay. I hope it's long and fruitful for you. Embrace and enjoy the journey. It's an ABSOLUTELY fabulous one.
Be safe, well and happy
Lotsa luv
Catherine
