What is family?

I just need to get something's of my chest. Ohhk. My mother moved in with me and my boyfriend about 2 wekas ago. She had got kicked out of her apt has no job no nothing. She right now is living off my little brother child support money and food stamps. She has a lot going on right now. She is a very strong lady. I have never seen her struggle this much in my whole entire life! When me and my siblings were younger she manger to do everything she could for us but now it's like she has giving u. She worries about my 2 brothers more then anything one is is 21 the other is 8. She'll give her heart and soul if she could for them. I thinks that's what's is stressing her out. My big brother the 21 year old does nothing with his life has no job no nothing. He really is a big bum. I love him but that's just whAt it is. So there is 5 of us. The oldest is 26. She has a husband a 4yr and a new baby on the way. My mother was living with her for a while but all hell broke loose because her and my sisters husband don't get along he is a disrespectful son of a b&$@(  anywho while she was living there those 2 would go at it everyday. My mother would come to my work and complain to me about what was going on. So one day when I had have enough I went over there to confront him about the disrespect and he didn't about the door.  So I took a rock and threw  it at their window now they are pressing charges on me. I find pretty funny tho. But the next day she went to go her stuff and now she living with me and boyfriend. I have told her everything I needed to about living in my house. She won't listen. She does whatever she wants and ask really ungrateful. She is just bugging me and my boyfriend. He keeps complaining about her to me a lot the time. idk what to do. I need help on what to do about her. Sorry for the long story. Just had a lot on my chest. I'm too young to be stressing like this I'm only 19 I'm still in school working and try's to take care of my family. Holidays are here and everyone are having fun with their families when mine are trying to kill each other. I just want a loving family ????
