Hon don't beat yourself up about it.

I say (often!) I suffer from "Foot In Mouth Disease". Luckily, since starting treatment for ADHD, my brain has slowed way down. I still do it occasionally, but my FIM incidents are fewer.

Put a note on your computer to remind you to read what you wrote before you hit "enter". I know it can be hard, especially when the conversation is moving so fast. I find reminders like this helps to make them habits. I work in a call center and have to watch my tone of voice and such ALL the time. Doesn't matter if I have a bad day, I HAVE to keep it out of my voice.

I have found PC to be a very supportive place and I have yet to feel as if I was being "judged". Hang in there and know we DO support you!
