Hey dramaqueenjs I feel like I'm parenting my nephew (which is fine - he's a kid) but also the rest of my family . . .I'm hoping that the meeting to provide supports and counselling for my nephew on Friday will help trigger some services for them.
I hope the meeting goes well. If somehow, you could get your nephew to stay with you until he graduates high school, it might make things easier for you in the long run. All the back and forth and drama with your sister is crazy making behavior.
I'm a dancer and an athlete so I run to try to burn off the stress. The benefit to the stress my sister is causing is that my run times are pretty darn fast right now.
Good for you

Exercise is a great way to tame stress.
My mother tries so hard to protect my sister all the time that I worry it does more harm than good.
I think you are right. Enabling is counter productive. I'm sorry that your mom isn't there for you. It has to be frustrating to see your mom be so consumed by issues with your sister.
I hope things go well with the Friday meeting. Let us know how it goes. Keep running and dancing.
