Yo said that much better than I did. I simply said "if it's too much for you, don't worry I'm used to it I can do it myself" which got her more angry because d9 would have to come with me and she needs to get to bed earlier than that.
In the end she asked me to ask a parent for help getting him a lift home.
I said it's an idea I'll try to get help with. Maybe I didn't validate enough before trying solutions. Thanks. This isn't easy.
