Everybody's afraid of change. It's completely normal. And transitioning and even the little things like plucking your eyebrows, take a lot of courage. I had the same problem, but I just did it. I plucked my eyebrows, started buying women's clothes before I was even on hormones and have worn makeup most of my adult life, though a minimal nude looks, which is what I prefer with just a hint of highlighting and shimmer. Though sometimes, I am much more of a blush slut. Mainly, I'm a total eyeliner girl now, and left the house without yesterday and nearly cried. But I improvised with brown shadow and a small eyeliner brush. A girl's gotta be resourceful.
But don't worry. You'll get there. No need to rush things, just do them when you feel comfortable. Honestly, maybe not. I just kind of started doing it and was so so so so nervous, but never received weird looks and it all worked out. You could wait to you start HRT and started passing, even if minimally if it is too hard. But eventually, you'll have to start tip-toeing into the cold water and then just dunk yourself under and immerse yourself into the waters like a mermaid who just wants to be a regular girl. < *see what I did there! He he he I used to watch that movie non-stop with my two BFFs, Julia and Becky, when we were 13.*
