You can still get the hair and fit! I always see these "unrealistic transition goals" and I'm like, "you know you can do that look without expecting you'll be as hot as a cartoon or model, right?"
It might even be that the look could never fit your vibe, but there will still be other looks that would work amazingly. I compare myself to others too; we all do it. Even super hot people compare themselves unfairly. It's just how we think about our own appearance by default.
Whenever I feel that way, I try to remember what it was like to hate literally everything about myself. If past me could see current me in the mirror, even though I'm still pre-HRT, she'd probably cry over seeing herself for the first time. I'm still motivated to look better, only now I don't feel hopeless because I appreciate what does work. This isn't easy at all, as you need to recognize and think critically about your own thoughts. Meditation helps, but it never comes naturally.
