Lasting Impressions

I've realized that one of my pet peeves is when people tell me how they think I feel. I value the opinions of others a lot...Probably far more than I should. So when someone tells me that I seem sad or something, I sit here and analyze everything and eventually come up with some kind of reason to be sad because they are of course right and why didn't I see that before? It's frustrating and I wish I could just stop. So just don't tell me how I feel. It's annoying. Thanks!
