Oh my. I could not believe this when I read this! As Taurie said, at 5'7" and 135, you are nowhere NEAR what any sane person would consider "big." You are quite small, actually! That is very hurtful of your father to make comments like that to you... I can relate; my mother has been extremely unsupportive of my weight loss, and it is very hard. You expect that someone who you love will be with you every step of the way when you're trying to do something good for yourself, but unfortunately weight loss makes people act really screwy. But you have every right to be offended, and you can rest assured that what he said was NOT acceptable (and certainly not true)! Hugs for you!
You can just use experiences like these to provide more motivation for you--every time you make a healthy decision, you are proving him wrong!
