Everything is out of control…

Everything seems to be slipping out of my hands right now. My relationship with my boyfriend, who was also my best friend. My relationship with my parents. My mom has just left the house. I am here trying to drown my grief somehow. I dont know what to do. I have younger siblings I should take care of right? But I need to be taken care of. My boyfriend is not understanding. he doesn’t even know what else I am going through. Im so lost and confused.
