MMOB or not?

My mom had a major freak out tonight in front of my nephews. Major as in screaming, cursing, and breaking shit.

This is going to be long.

Ok, so my mom has always been, well to put it nicely, a little off. She claims that she has been battling depression her entire life. Well, she won't go see a shrink and the pills our gullible doc prescribes her really don't seem to ever work. As soon as she decides that the pills aren't working, she takes herself off of them. Doesn't go back to the doc so he can wean her off of them or anything, like a normal person would.

She also does this thing where whenever she feels like she isn't the center of attention all of a sudden she is deathly ill. The best was one Christmas when I was a kid, she decided that she was sick and went to the ER. She convinced some poor ER doc to admit her overnight for observation and missed Christmas. Sadly that is one of the few Christmas' I actually remember.

Anyway, sometime over the weekend, she decided that her current meds weren't working and took herself off them. On Tuesday, my dad had to go see a specialist about his shoulder in the city 3 hours away. My mom was supposed to go with him but ended up staying home so my baby sister didn't have to pay a sitter to watch my nephews. She HATES it whenever my dad does anything without her and makes life miserable for for anyone who crosses her path for a couple of days afterwards. So I expected her to act all bent out of shape when I called that afternoon to find out what the specialist said but I underestimated how bent out of shape she really was.

I called the house and my oldest little sister answered the phone. I asked to talk to my mom. She gave the phone to my mom and this was the conversation:
Mom: Who is this?
Me: Who do you think it is, it's me. How did Dads appointment go?
Mom: I don't know. Ask him yourself.
And she hands him the phone. I talk to him for a minute and then go back to working.

After work, I picked up the boys and they wanted to go over and see my nephews. I saw my mom standing at the front window when we were walking across the sidewalk. By the time I got the boys inside, she had ran off to her room. I go into the living room where everybody else is and the first thing they tell me is that mom is "sick" again. Ok, well, whatever. We said hi to my nephews, I tell my dad about how the cat caught his very first mouse and we leave.

So now it is Tuesday. The boys wanted to stop by to see my nephews again so we did. My dad was standing at the stove cooking dinner and as I walked by, he told me that I probably shouldn't stay long. I asked if everything was ok and he told me to go talk to my sister.

According to my sister, my baby sister dropped off the boys before she went to work. My mom must have been shitty to her yesterday too because she had a "talk" with her. My baby sister left and my mom comes roaring into the kitchen, screaming and cussing (my mom isn't a curser) about something. I have no idea what that something was, my grandma butted herself into the conversation before I could find out. This is when I find out that my mom had decided to take herself off her meds. Anyway my mom started grabbing the kitchen chairs and hitting them on the ground. She broke 6 out of the 8 chairs and ran back into her room. My sister said it was chaos.

That whole meltdown happened in front of my nephews. Now, the baby is barely 4 months old but Ollie is 2 1/2. He doesn't need to see that shit. I know I would have flipped my lid if my boys had seen something like that from my mother. My oldest little sister is 24 and was scared. I can't imagine how scary that nonsense would have been for a 2 year old.

It makes me sick to my stomach that I didn't pack up those boys and bring them home with me. But the only thing I was thinking about was getting my own boys out of that house before something else happened. If we are ever in that situation again, I will be bringing ALL the boys over to my house.

So now I need advice. Do I talk to my baby sister about finding a different daycare situation ASAP or do I keep my nose out of it and hope that she does the right thing?

Do I try to talk to my dad about maybe forcing my mom to get some real help (an intervention or maybe even committing her temporarily) or do I keep my opinion to myself and hope somebody figures it out?
