who's the real selfish one here?

I'm sick . I don't know what exactly is wrong with me but since yesterday my head has been hurting si much that it makes me dizzy , so was mystomach. Today , even after all the pills , my head still hurts , I'm nauseated and every muscle and bonejoint in my body hurts. I called my aunt to tell her I can't take Cristi (her son) to his swimming lesson today because I don't feel well. And then she goes and asks m grandmother to take him; my grandmother who can barely walk and doesn't even know where the swimiming pool is. Why? She's home today ; she could take him ; she's his mother after all. And besides , it's not like it's the end of the world if he misses one lesson. But I bet he started making a fuss about it , that he wants to go. And so everyone else has to go out of their way to make his wishes come true. He's just to spoiled. And I hate the fact that everyone has to put aside their own problems just to oblige him. I hate the fact that he always comes first nomather what and that now my aunt is blaming me that her litle "prince" is unhappy now. I'm supposed to just get out of bed , even though I can barely stand , and take his highness to the pool. She didn't even bother to ask me if I'm gonna be alright , if I have medicine in te house. Nothing. Not her , not mom , not grandma. It makes me wonder , am I really familly to them or just a servant?
Yeah , I'm sulking like a litle kid right now , but it feels bad to see how they don't care about me at all ; they only care that the litle spoiled brat gets his lesson. And I also hate myself for feeling this stupid jealousy but I can't keep it down anymore. I always told myself that he's just a kid and that it's natural to care about him more than about others. But when they turn me into the bad character here because I didn't take him to his damm lesson it just gets on my nerves. It's not like I didn't take him cause I didn't feel like it . I'm sick for crying out loud.
God forgive me but sometimes I hate this familly.
