I am so so annoyed. My sister has made fat jokes at me for ages and I've tried everything I can think of to stop her, like, ignoring it, laughing along, or telling her that they are just cheap shots but nothing has worked. and Now, because she does it all the time everyone else seems to think it's ok and it's not, now it's like, everyone, and just recently my best friend has made a couple of jokes and it's so annoying because like, sometime last year I told her that I was so annoyed that my sister had encouraged other ppl to do it and she was sypathetic and NOW SHE'S DOING IT TOO!!! And I can't say anything because my sister will contradict anything I say and it's just so frustrating. Every time she does it everyone laughs and I feel like bursting into tears. I feel like crying right now because I just got off the phone from my best friend which is where my sister came onto the conversation and joined in calling me fat ass and stuff and my friend laughed. If I ignore her she calls me more names and I can't see any way out of it except losing weight and I am but it's a slow progress. All my friends including one I haven't seen in ages is coming over on monday and I dread to think of what she would think if my sister started saying things. I should stop this is getting too long but if anyone has any ideas or wants to vent about annoying small minded ppl feel free to reply.
