I had to get it out.

So for a couple of months my mother is been acting really weird!
She is 48 years old and got a boyfriend who's 27 years old
(I'm 25 and my brother is 30 and my lil sister is 16...)
The thing is she lost weight she was like 125 and now I'm pretty sure she's only 90lbs she's really looking sick and she lost all that weight for him cause he love his women thin and tight (That's how he said it actually) She pushed me and my brother away, telling us she doesn't need help cause i can clearly see (cause I've seen it allot) she's depress and probably drinking way much more that before.. She said that now nobody need her to be a mother so she an be a women.. My 16 years old sister live with them, my mother is always gone with her boyfriend when she got money (cause he doesn't work) they leave to go on a ''auberge'' for 3 days without giving money to my sister for food or whatever.. My uncle used to live with them with his son who's 14 years old but they fought yesterday and she kick them out of the house, so i got my cousin in my house (I live in a house with only one bedroom which is enough for me and my son, but I'm moving out on July cause I'm pregnant and needed another room for the baby) but the thing is my uncle was buying food for my sister and his son and was taking care of her... Now she got no one my mom is only in her house when she have no money anymore, so she'll be gone the first of May cause she'll have like 1600$ in her bank account. And my sister will be alone.. I can't tell her to come live with me cause we got into a huge fight and as a teenager she is still mad at me.. But it's just I'm stuck mother keep calling or (or texting me) for
1)telling I'm a horrible daughter
2) crying on the phone cause she said she need me that i shouldn't turn my back to her..

I just told her that i wanted a break I'm 21 weeks pregnant, I have a two years old to take care and now my cousin.. I don't have much money. I just need a break.

I can't ignore her cause i don't know who's calling me on my home phone, i do on my cellphone but that's it.

I just.. I don't know what to do how to think or to react.. I don't know anything anymore right now my brain is kinda dead..
