That is a huge accomplishment, and don't let any little meanies take that away from you! That was really crappy of those people. Ugh. People can be so horrible.
But it is also good to remember that not all people are jerks. Just this Sunday I had a man come up to me in the gym and say it was good to see me back at it, and good going. For all the jerks out there, there are also people who will cheer you on. Hopefully you will meet some of them soon too.
