Attacking the Critic

My daughter and I started weight watchers last month with great results so far. My husband and son can be very rude and make sure they comment on something if they think it's not in our "diet" plan. With weight watchers you can eat chocolate, chips even fast food but in moderation. I know that they are just trying to help us stay on track but I get very defensive since there not bean poles themselves. I am attacking the critic using verbal aggression because its something I don't want to hear, which can turn into an argument. My husband and son don't mean to hurt my feelings but they like to use sarcasm which I take the wrong way. I found out with me that if not comfortable with something about myself its easy to get defensive and feel threatened even though its my family and they would never try to hurt me. I need to learn to just brush this issue off and not get so worked up about it. I'm a person that can take a lot of jokes and sarcasm unless its something that I'm trying to change and I'm insecure with.  I'm learning to sit back an evaluate the whole situation before I make a rational decision that leaves everyone feeling upset. We are both down about twelve pounds so I guess in time they will learn to shut themselves up once we reach our desired goal weight!
