Hi Amanda,
I pretty much prepared myself for whatever changes happened well before I started hormones. If my face completely morphed in 1 month or 1 year, I was ready. If my breasts grew to C in 6 months, I was ready. I found that by not expecting any changes but being
prepared for them really helped me. I came out to everyone close to me at the same time I started HRT so that the changes they saw would be self explanatory. I would rather have done that than worry that people know something is going on with me.
In your case, I'd ask some questions and just kind of reevaluate where you are with transition and get on the right track for you. Are you prepared financially and emotionally for the physical changes? Who have you come out to? How much time were you giving yourself to notice changes? Remember, you are FEELING changes. Those changes might not be too obvious to other people who know you.
Right before I transitioned I took an Excel spreadsheet and basically made this timeline thingy of when I thought all of this stuff would occur, like Date Started, Date Completed, etc. Obviously, you can't plan for all the stuff to happen on X date, but at least it helped me organize transition into smaller steps. That's kind of what it is, a bunch of smaller steps into some larger steps right (ok, wayyy over-simplified, but you get the point)?
So don't freak out Amanda. The changes you see are probably mostly in your head unless you have everyone around you going "whoaaaaa, what's going on with you? you look like a girl, OMG, what's going on?" I'm sure you were expecting the common questions after a few months "hey, something looks different about you, what is it?," "did you do something different to your face?," etc, etc. I didn't see before and after pictures, but hair and eyebrows make a big difference between someone seeing you one way (boy mode) vs. another (awkward in between stage).
I think probably the best advice I got on the period right when I started HRT and started seeing some changes was to "man up." Lol, funny term, but basically, you KNOW you are changing, you are planning on it. If you aren't FT and you are wanting HRT to make some physical changes, let's say for a year, then don't make obvious feminine changes to yourself. As an example, I was having my eyebrows done, but right when I started HRT I had them done really fem. I was wearing really androgynous clothes, I was flat ironing my hair, etc. and this was before I had come out some people. So they'd see me and be like "um, yeah, what's up?"
If I really planned on getting through a year of HRT without throwing people off, I was approaching it the wrong way. The changes will happen gradually whether I'm expecting them to or not, so I figured I'd just stop pushing the limits and just let it happen. Then I came out to everyone. Now I can pretty much just do whatever without thinking who knows, who doesn't, what changes are happening to me. I know my FT date, that probably helps a little. Anyway Amanda, don't freak out or get really worried, just reevaluate and see where you are and make changes if you need to
