HRT questions??

Im about to start HRT (mtf21) and im really curious and rather scared of the transition process. Like if ill change the way i want to without surgeries.

I mostly want to know about fat displacement. I know the chest will change but where does the fat come from?

Will i get a more femenine "hourglass" figure (which would make me extremely euphoric)?

And my facial structure. My biggest source of dysphoria alongside body hair. Will estrogen make my face naturally more fem and will my body hair get thinner/stop growing, etc.??

Note: i live in MA which by law insurance has to pay for my HRT, bottom and top surgeries. So if i have to get electrolysis, FFS, and vocal fem surgery ill do those if HRT doesnt touch them
