Please don't beat yourself up. You made a mistake and I don't think that many advil will do more than give you a stomach ache, you could call poison control to ask, you don't have to tell you did it. And really, what' s so bad about yelling at the shower? It was frustrating. Just so you know I enjoy reading your posts. Be good to yourself, what would you say to a friend if they felt like this? Treat yourself as kindly. You deserve it.
