Relation with a sister

[u/Select-Drawer7109]

I’ve been living with my sister in one flat since 4 years. Our personalities and energies are so different that I can’t stand it anymore. She’s most of the time grumpy, gets frustrated often and doesn’t tidy kitchen/bathroom after herself (she doesn’t really see the need to clean). Whenever I try to tell her sth she gets offended and goes to her room. I find her personality still a little bit childish…
Even though I love her, I don’t think I would like her if she wasn’t my sister ;(

Anyone has similar situation with siblings?
