How do single parents do it?

I always knew that single parents had it VERY hard. Like verrryyy. My mom's been in the hospital for 3 weeks now. (long story short, it was couse of very high blood sugar, and she is doing good, but still in there for observation). And becouse of that, i (14, M) had to take care of my other 2 brothers and the house since im the only one who can cook, do the laundry, the dishes and all that. (For anyone wondering, my sibling (same age) and my older brother (18) can not do those things. But all that mixed in with school stress, caused me to feel like my life source is getting sucked out of my body by a giant mosquito. I cought myself dissociating more often, and i ask myself "How on earth do single parent have a job, then enough energy to do everything, and then still be a good parent to their kid(s)?"

(Im sorry for any bad grammar, english isnf my first language.)
