I did that with myself. Decided when I was 16 that I WAS going to change my behaviour to fit in better (and decided that I wasn't going to let depression or my family win...).

So by now (omg it's been about half my life) I've met a lot of challenges... that have taken a looot of small steps to reach. Eating out on my own was really tough. Started with food courts, then fast food places, then take out, then a restaurant that's fairly busy/quick, and now I can eat at almost any restaurant on my own. Still need to have a book or my phone out though. Also once or twice have managed to go into a pub and get a drink at the bar by myself - once I even talked to the bartender!! (Startled myself on that one! They started the conversation but still!)

A big one for me was going to the movie theatre on my own. Holy moly was that hard!

And making a hair appointment. And going to the doctors. And travelling. And using a taxi. hahaha.

So many things that shouldn't be a challenge but totally are.
