Being happy now, doesnt mean you have to take anymore steps.
There is no rule that says you have to go further.
And just because sombody ells does somthing doesnt mean you should.
Sometimes we get it into our heads that, Im transitioning and this is part of transitioning, so in order to transition must do this. But transition is a completelly personal thing.
If you dont need to go any further, then dont. Dont feel as though you have to do somthing in order to validate yourself as a person.
If you are afreid of regret, then I sugest not going forward untill you are completelly comfortable with it, because if you go forwards with these concerns, should you regret it, you would never forgive yourself.
So basically, If there is anything that you will regret. should that happen, you will regret it.
For example, I know this might not happen, but if it does Ill regret it.
I think that when you look at it like, I know this might happen, and this might happen and all of these oter things might happen, IS any and all of these potentioally happening to me, a risk I want to take?
If not do not. Thats my advise.
