Help for this darling boy

Hi guys! My name is Kalista and I am a 20 year old sister who just got custody of her darling little brother and I’m in need of some money for housing, a new bed for him, clothes and food. Anything can help it’s just kind of rough right now my mom is going through a lot she’s delt with substance abuse all of her life and currently I’m sleeping on the floor so he can have my bed in my studio apartment. It’s very cramped and my lease is ending soon. Thank you for your time and bless you all.
