So, I have two children from a previous marriage and one child from the current relationship I'm in. My BF has a daughter who is 11. When she is around, I'm a total b****. I get frustrated and get anxiety attacks for no reason. She isn't a bad kid - BUT she shows off. It's mainly "look at what i got" or "did you know..." I really can't stand it. It might sound shallow, but her appearance also frustrates me. She's overweight, wearing a size 12 women's when she was 9. I'm overweight wearing a size 10 after 3 children and I'm only 5 feet tall.
