Hi annoyedgrunt, I'm sorry you were having such a hard time
Hoping things a a bit better for you now, but if not, or if you want to talk.............
And if there's another night like last night............you know, maybe your family would like to/want to know if you're struggling so as they could try to help/support you???
And the causing a scene.........I'd say that the way you're feeling is much more important than/matters much more than, the idea of "causing a scene". In fact I wouldn't even see it as causing a scene........you shouldn't have to feel bad about expressing the way you're feeling when you're struggling, you deserve their support
But..........if.........as I obviously don't know your family............then maybe an online crisis chatline???
But either talking to your family........an online to a crisis chatline.........to us.........or to someone else..........please try not to feel you need to be alone with your feelings, they matter!!!
