I'm sorry this is happening for you. I and several members of my family have a facial expression that evidently looks like we are frowning if we aren't engaged in conversation. I, myself, am not one to walk around with a grinning idiot expression.

Anything that makes other people uncomfortable, especially speaking the truth, will usually get twisted to be something wrong with you. This may very well be why your family is against your seeking counseling.

Maybe you can take some comfort in knowing you're more honest than them.

This is just my opinion and experience...I could be wrong
