For me, not transitioning earlier and just dealing with my dysphoria (by simply ignoring it and hoping it would go away) has cost me valuable years and left me with more to undo. I am at the point now where I have to do it or I won't be able to function in daily life. The expectations of others and that of society have kept me back and left Ms Kate imprisoned in this body. She made an escape attempt once with the help of some friends from the Pacific, but while freedom was sweet, with it came reality that living on the lam was no fun. Now she's hoping to with the help of some therapy to finally negotiate her release.
But ultimately it's your choice and only you know what's best for you.
As for becoming more ugly, from what I've seen that's really up to you. I've seen some magnificent transitions so anything is possible.
