I think you need to be easier on yourself, friend. You’re going to have rough days but letting those dictate your whole outlook just isn’t fair to you. I agree with the other post here saying to take deep breaths and slow down a bit when you’re talking. What’s the hurry? Take your time and say what you want to say. Would you tell a guy in a leg brace who’s walking a little slow to get the hell out of your way? Hopefully not so don’t expect folks to treat you rudely either.
