Miswimmy is right -- you have to remember that while your feelings may have been invalidated, YOU have NOT been invalidated. Only your opinion has. The others disagreed with your opinion ONLY (I agree with you by the way) but they don't disagree with you as a PERSON.
Sometimes it's hard not to take some of this stuff personally. I have a tendency to do this alot too. I'm pretty think-skinned, so I have to be careful about stuff like that. I need to think about what I'm getting my nose bent about -- is it personal or not?
God bless, my friend and please take care. Gentle hugs, Lee
