Disabled and feel unloved by siblings...?

I have a sibling that doesnt care about me, my youngest lil bro, or mother. Parents are getting a divorced. my mom provided him everything throughout his whole entire life and all he do is take advantage of her kindness and hospitality. I cried when i kicked him out of the house. he once moved in with us for like a couple months and now lives with my dad. even though he's bad and all i still love him. you should express your feelings. tell your siblings how u feel being mistreated.
