Hi Beanbag0

It sounds like a very frustrating experience at home. I hope you know that you are not the reason that your parents fight. That is their doing and it is their dynamic. I don't know if the holidays has any added component where you live or in your home but it affects me. Your weight and anxiety cannot ruin anyone else's relationship. Please don't think that you are the blame. I think you sound level headed and I appreciate how you care about your brother. Is there anyway you can remove yourself from their arguments? Can you go to another room or do something with your brother that is positive? Can you tell your parents how much their arguments are hurting you? I hope it gets better for you.
