Welcome beurry,
It looks like you have a good start. Baby steps are a healthy way to go. There seems to be less regret later when approaching the rabbit hole that way.
Job and age are two things that seem to worry many of us. Job, well, have you checked to see what your State and City's policies are? Have you checked to see what your company's is? While it doesn't make the interpersonal any easier, it is a pretty easy thing to see if you are legally supported.
I read awhile ago a post on here. They suggested that no matter the age, every transgender person approaching transition wish they started earlier. 60's, 50's(yup thats where I am and so wish I had realized sooner),40's, ....right on down. The post had quiped that if they started hormone blockers at 7, they wish they could have started at 4. Bottom line you will hear again and again is that it is never too late if you need to. I hate how I think I look and am not presenting in public yet myself. However, I don't know that I have a choice. If I didn't make this step, I am not sure I could pull myself out of a self destructive spiral.
On a brighter note. There are a lot of people who are supportive at many steps of the transition here. Welcome, join in and don't be afraid to ask both hard and seemingly easy questions.
Wishing you love, acceptance and a smooth journey.
With warmth,
Joanna
