My life just did a backflip into the abyss

Hey guys, never thougt I would post something here.

I am not feeling suicidal (yet) but still dont know where else to ask for help/advice. (Sorry for bad english, Im rushed, not a native english speaker and at work)

The last week my father got sent to prison for some kind of fraud of 15 years ago, I am 21 years old and have to take care of the family business wich has been going from bad to worse and we have some realy big debts. I have no freaking idea of how to run it, my family is fighting between each other to see who can help my father better and nobody ends doing anything, I have to work 11 hours a day so my time to try to help is not really big.

I also have one little sister (11 years) and a half sister (1 year), my mother (who is tottally NOT fit for child caring) is trying to take my lil sis from me, the mother of my half sister is trying to help me but... she is an asshole, she does not knows how to ask for help and people are really angry with her now, I tried to act as intermediary but now nobody wants to help me.

The lawyers say that my father will be out on monday but they have been saying "he will be out tomorrow" all week. I dont even know if after this we will be able to keep the family business, maybe I should just sell all our merchandise, pay for my father to get out and tell everyone to go f#ck themselves? dunno I feel like thats a bad idea becouse I made it in this nervous state.

And.... thats it. Im scared, I dont want to lose my lil sis and... fuck.
