Welcome.
Working on transitioning is better than doing nothing, but it takes one step at a time. I'm fairly new to this, too, so I don't have the experience of some of the others. Still, what works for me is to just take one small step at a time and see how that goes. I try not to look too far down the road. Just a step at a time.
BTW, I've known a lot of very tall women, especially about your age. I once had to supervise a group where the males had to be 6 feet tall to get in. I noticed with a little surprise that the one woman in the group was taller than any of the men.
Good luck.
