About to lose my shit someone help

Ok dont judge me too hard ok. I have 3 cats all rescues I have a 7yo cat and 2 8 month old kittens. We got the older cat when I was 13 weeks pregnant. Because well she was going to get put down and we couldn't allow that. And the kittens we found in a bag on the side of the highway. Now fast forward to the past few weeks. They are so spoiled. And varry well fed. But heaven forbid that we dont re fill their cat food dishes all the time. My older cat will come into my room while I am trying to sleep claw at my bed. I tell her to go away she gets what the vet said was the teenager persona and stresses herself out to where she rips out her hair and throws up every where. (Vet said she is perfectly healthy). Now for my kittens and with them its really hard not to play favorites because one is mute and dosen't bother me while I am doing anything she just likes cuddles. Her brother on the other hand is a pain in the ass if I am cooking he is under foot. He looks so offended when we put him off to the side and our attention is not on him. He begs for our food keep in mind that he has his own literally 7 steps away. Bit the fun part is when I go to feed them theh act like I haven't fed them in days 🙄. I have to tell my company that they are not starving they are all just trying to kill me at 3 am in the morning. And idk what their problem is. I might make 2 of them in to kitty tocos(its a joke I wont hurt them) I am honestly thinking about re homering my older cat. Just because of her teenage persona. But I love all of them even if I threaten to make kitty tocos out of 2 of them. I dont know what to do I am so tired of cleaning up at vomit and telling one that he is not a dog and not to beg. Lol my cats from hell
