slow down, take a break. no need to go all the way back to start just because you get cold feet. just take some time to think about it again, or try not thinking about it if that's possible for you. most mistakes can be forgiven, some of the people you've come out to would probably be annoyingly happy if you told them that you were mistaken about being trans. so don't worry about that part when you think about it, you can go back at any time before surgery. will only cost you a little if you've gotten far enough into hrt that you have breast tissue that needs removing in order to be able to take off your shirt in public. anyway, it probably won't be difficult at all to leave the path of transition and take the cisgender road through life.
which means you can take all the time you need to think, get cold feet, get over it (or not), try something different, go slower, take a break, or whatever really. so don't panic.
feeling feminine is probably not part of the definition of "woman". either you are, or you're not, or you both are and aren't or a few other choices as well. it can take some time to find out, but in the end, it's mostly about how you find it most comfortable to live. it could also be a question about body parts that you do or don't want, or hormones that make you feel comfortable or totally stressed out or anxious or other things. it might be worth giving hormones a chance. if you feel less negative with female hormones, then that might be all you need. maybe you don't really think of yourself as one gender or the other, but just need slightly different chemicals in your blood in order to feel comfortable in your own skin.
you won't really know without trying, so think about it for a while more before turning back. starting transition all over again would probably be something of a hassle, so at least think about trying stuff just to see if anything makes you feel better or less bad or somewhat ok. you can quit any time if you find out that it isn't right for you. or you could find out something rather gender unspecific like, it's less bad than the other choice. some choices aren't between good and bad, there are times when one instead has to choose the lesser evil. maybe you're in that kind of position, for all that you know right now.
but no matter what you find out, the easier cisgender road is always open. most people would be happy or relieved to see you back on it. and many of us here would rather see you happy than stick to a bad choice out of a sense of responsibility. for my part, you'd be welcome to leave and come back as many times as you need. don't let the pressure of other people's expectations (or what you think they are) cloud your vision. only you can ever figure out who you really are, if that takes some trying and failing, that's ok too.
