There was a period where I was going out in public and it would literally take me 10-20mins to get the courage to open my front door to walk down the driveway to my car. That was the beginning of summer this year for me.. As summer passed and I started to find my "look" and attitude/confidence it got better and better.
For the longest time (even as a guy) I could never find my inner "Don't give a f**k". I always cared what people were thinking. I have definitely found my inner DGAF now.
Coming out at work was painful. It took me from April-Oct to come out to everyone gradually. I got myself incredibly worked up and stressed out for no reason before sitting down with each person in the office individually. Every person (except 1) I told was either cool and supportive or just didn't care because it didn't affect their life. The one guy that does have a problem with it, well I didn't like him before coming out so there is no love lost there.
I am pre-HRT, pre-op, pre-anything... living FT. And honestly, I feel more comfortable and confident now in public than I ever did presenting as male. As a male I had social-anxiety, always wondering what people were when thinking they looked at me, wondering if they were judging me, etc etc...
Now, I just don't care. I go out for lunch 5 days a week with another co-worker (male) and I don't even notice if people are clocking me let alone looking at me. You can't please everyone in this world... EVER. There are 7,000,000,000+ people on this planet, are you really going to stress about or care what a few ->-bleeped-<-s think or say about you? They are a**holes for a reason. There is something in their life they are trying to compensate for by trying to make you feel like ->-bleeped-<-. They will make fun of and be-little ANYONE (cisgender or transgender) who they feel they can bully and who are not equal to them, just so they can inflate their fake egos a little bit more. Flip the script on those pricks. Confidence will take you along ways in transition.
