What you're experiencing sounds similar to:
Personally I don't use beautify/face-gen apps as I had a terrible experience on Insta and Facebook where I was glued to my feeds because I was depressed about my current state of life.
While I can't say for certain what's the best for you, what I can suggest however is to talk about about how you feel with your wife and perhaps with your close friends and anyone else you can trust as it seems like you want more encouragement to be able to perservere as you transition.
Either way from me to you:
YOU GOT THIS!✊✊
Even though you currently don't look as how you wish at the moment, you've got a great wife whose one of your greatest supports and you've got a great starting plan for getting there!🌻🍀✨
Totally fair🤗🌻
