So, I've just joined the group and would like to say hello.

I have been a Step Mom legally for 2 years but DH and I have been together for 11 years. I have known his kids since they were 14, 6, and 4. They are now 26, 17, and 16. We've been through a lot and for the most part I've suffered in silence but lately I feel like I've needed some help or, at the very least, someone to vent to. Which is why I'm here. 

After the pandemic, 6/8 of my boyfriend's children (ranging in age from 12-18) came to live with us full time. I have no children of my own besides my cats. His kids are good people, but they are very LOUD and sing all night long. They also stomp around like elephants and throw footballs, etc. It's kind of like being in the real life Sound of Music, except not anywhere near as fun!!  Plus they have completely destroyed our house. My only safe space is our bedroom, but they come in while I'm at work and have taken some of my things.

Alright here it goes. First I'll give you the players in this game and some background info. This might help with some advice I'm needing.
