Yes I practice mindfulness, and yes it works, but only if you actually do it. It's no good just going and saying oh I have problems and this isn't helping. It's not supposed to help in itself, it's a took to help you exist more efficiently, more in the moment and more focusedly. It won't help you not have court proceedings or not have your partner leave you, but it will help you be able to deal more effectively with those things when they do happen, but only if you actually do it, and sorry to say Old Geezer is right, you're not approaching it correctly for it to help.
