You might be able to talk to your 14 y/o, since your kids are already picking up on signals that something is not "right" with mom. Is your partner around to help support you on this Mother's Day? Perhaps you could wish for a sleep in kind of morning, then let the kids do what they need to do to show you how much they love you. Wish for the quiet day. Sometimes you have to be vocal and tell people- even your kids, what you really want (of course, with some tempering).
You know all too well, what it felt like with your own mom.
Hoping you get what you wish for tomorrow.
