Hugs to you !!
When something comes easy to a person it is VERY difficult for them to understand just what your going thru. My hubby is very thin, only recently has he put on 20 lbs b/c he quit smoking. He's been struggling to lose it for over 6 months now and every day after work he say to me "this is hard, I can't lose one pound and its very frustrating" so my reply to him was "WELCOME TO MY WORLD!!!" Its hard for someone to help unless they've been their themselves. My dh has never said to me lose weight although I know deep down he wants me to, I mean who wouldn't, its a healthy way to be.
How to become thick skinned you ask. Thats gonna take some time. First thing I think would help is accepting yourself for the way you are. Tell yourself okay, this is me, and I'm okay with it. I can chang this if I want. Nobody can do this for you. When your hubby says stuff to you, instead of the instant... he is attacking me. Listen to his words and say YES, your right, he's right (I do love salad), he's not saying this to hurt me, he loves me and wants to help. Instead of the instant disagreeing, stop your thinking, shake your head yes, and just think about the exact words as if your saying them to yourself. By the way, why can't you have a burger ? have a salad and 1/2 a burger. Don't punish yourself.
I know this is hard b/c I eat at every single emotion too, I mean I don't even need an emotion
Give yourself a little breathing room Island, if it doesn't work today, try again, never stop trying.
I used to be so sensitive, I mean real bad but I guess w/age and experience, it doesn't seem important to me anymore what people say, or how they say it. Its just not worth it. Whats important is me, and my life.
Hang in there !!
