What about me? Why does it always seem that nobody cares about how I feel? :'(

Nobody listens to me. And kwa nobody, I mean my family. They always ignore everything I say au trying to say. And whenever they do listen to what I'm saying, they end up laughing at what I say. It's so annoying and irritatting. It makes me so angry. It makes me want to swear and I don't even swear because I know God won't like that. Every time I just so happen to say something bila mpangilio my mom goes,"AHAHAHA Valerie alisema this and that!" and she goes telling other folks what stupid thing I say and they end up laughing at me too. I can't stand it when she does that. I'm always telling her in the nicest way and trying to be as calm as I could,"mama, please don't do that." and she says,"ok I won't." and wewe know what? She doesn't listen. She does it anyway. She did it again today. And I told her the same thing," mama please I told wewe I do NOT like it when wewe do that!" but she wasn't listening. She kept telling on me anyways. And now she in there in the living room having a good time watching some movie with my niece and nephews while I'm sitting here all alone in my room just crying and crying my eyes out. Every time I try to tell her how much it bothers me, all she does is fuse at me about it. She doesn't even say sorry about it. She's not the only one who does this. As far as I know, my sister does it, maybe both of my sisters does, granny does it, my cousin use to, but not much anymore. Not because of how it makes me feel. It's because me and her grew up so she must've grown out of it. This has been going on for years. I hated this sense I was a little girl. I'm 20 years old now and they still won't stop. It's like they don't care how it makes me feel. Why does nobody listen to me?! I have feelings too! And family are suppose to understand each others feelings! I upendo my family very much but it just makes me sick! What about me, God? Please answer my prayers! Please make them stop laughing at me bacause of the bila mpangilio things I say! >:'(
