Fucked up living situation part 2

My stepmom is turning my dad on us with her stories. She’s unfair to the girls and favorites her own daughter. For example:

My sister needed rat food and got yelled at for money and then my stepmoms daughter asks for random stuff to buy for a rabbit she stole from the neighbor and they give her their card. (they found the owners and ignored it 😡)

My step-sister is 13.. and her mom lets her have jul pods and take adderal, smoke weed and have online sex with her 21 year old boyfriend who they “really like” I’m saying she lets her because she knows all of that and doesn’t do anything about it. And my dad won’t because “that’s not his child”

My step sister goes through all of our stuff and steals shit without even caring that is obvious (she took a box I painted that had weed in it that they got for me) .. smoked all the weed and left it hidden in her room. Yes. I went in there to find it because it was missing and I have no idea how long she had it because I don’t smoke!!!

My sister Kaitlyn just started living her because her mom and her bf has a knife fight and dad finally got custody and she’s so filled with anxiety and depression it breaks my heart.

I really need advice. I have no idea what to do. I clean up after myself, clean the house, cook for the girls because my stepmom buys no food besides junk food and goes to the store without my sister even though she asks to come.. I pay my own way, I NEVER ask my dad for any money, I’m working a lot I don’t need it.

My dad is a lineman, he always brags about how much money he makes.. literally gave my stepmom $6,000 to spend for herself -my sister told me. And he’s throwing a fit over whatever my sisters need but gladly gives it to step mom and her daughter.

I came here to get to know my dad. He was nothing like this when I visted. He always preached putting his daughters first, having a no stress house.. I just theres SO MUCH little details I haven’t even told you but life is a mess. I’m looking for my own place, I want to take my sisters with me.
