Hi Sam
You don't want to overtaxing your mum, so you make a delay in coming out.
I think, the moment you want to tell is never a good time because there is always something going on.
On the other hand, when you're fully accepted, it was a very good time.
IMO you're giving it some time to collect some courage before you tell and that's very understandable, because there is never an easy way to come out of the closet, never, it feels like you are standing there naked in front of a bunch of people.
But, there is some good news about it.
The relief when everything is done.
I notice, when I read the stories of people that there is some quiltfeeling thing because some people are upset or something when they will hear the news.
But, did you ask for gid?
Nobody did, everyone of us would rather be born in the right gender, but, nature sometimes makes mistakes and thankfully there is something there could be done about it.
Take your time, and when you feel you need to say, just do it.
A lot of strength wishes when you reach that point.
hugs
Annette
