Tired af!

My mom always takes decisions alone without considering other people's feelings. I feel like she wants to make her family happy, forgetting about how we(as her family) feel about things. She fetched her brother and her sister's son to visit us during the holidays. This really makes me so uncomfortable and unhappy. I don't even like the way I've been rude to her lately. Now it's our(my siblings and I) to take care of her family. Her sister's son is low-key abusive to my lil sis. He makes those unlikable moves to hurt my sister. With her brother,it's so hard because they're always expecting to eat nice things. Even when we cook, the food is too little. I sometimes eat nothing during the day and eat once when I'm about to go to bed. The saddest part with all this is that my mom is so ignorant, or should I say is noticing nothing. I hate being at my OWN home right now. I think I'm even losing weight, and on the other side, my sister is gaining.
