BREATHE, just take a few big deep breaths, it IS ok, you are ok. Your mind is freaking out on you right now. Probably alcohol induced. Maybe you didn't say the right thing (so what), but his reaction was totally out of proportion. I find that when people react that way, its about so much more than you and what you said, he has personal issues and you just triggered it to come out and he is lashing out at you. He should not behave that way, its out of order & out of line.
You are NOT ridiculous. He is likely sufferening just as much if not more. You have to speak kindly to yourself. And be kind to yourself and soft and gentle. Don't beat yourself up. And its like that for me too, I'm doing really well & out of nowhere spiral down back to where I was. The only thing I say to myself over and over is I will always get back up. It will be hard but I will. And on my good days I tell myself, how strong I am because I do that. Other people don't have that struggle and don't know what strength it takes to keep fighting.
So keep fighting. Alot of times, with each period of getting well, I have learned something new, or found out something else. So maybe you just have to do some work right now on you. But start a commentary in your head that you are smart, strong, cariing. Truely, his anger here is not about you, just directed at you. How are you this evening?
