A Broken Promise

So I've recently made a mistake. Broke a promise. The kind of pain that eats away at one's heart when they make such a mistake as this is very painful. I can literally feel it eating away at my heart, mind and soul. The only thing I can think of is admitting to the person/s that I made this promise to and tell them the I've broken it. One thing that I used to pride myself on is following instructions and doing what I was told. Normally, I ask no questions, I just do it. And maybe it was from increased stress, and being completely overwhelmed that I decided to rebel. The sad thing is, I wasn't rebelling against the person/s I made the promise to. I was rebelling against a certain member/s of my family. To not be under his thumb anymore. To be my own person and make my own decisions and mistakes...to learn from them. But this mistake...is too intense. Too much to take on. I too hard to admit. I asked what should I do about my overwhelming amount of stress and someone told me to relax and breathe. Maybe the consequences wont be what I fear. I just need to relax for now. So think of me in your prayers. Give me the strength for patience and relaxation. Thanks!
