I totally get it. Its absolutely exhausting being the responsible parent. Having to answer every single phone call, be available 24 - 7 because you are the only one your kids can count on, not to mention handling the mood of the house and those living there to keep everyone safe. Please take care of yourself and I really hope you have a couple of local friends that you can vent about the situation and who have your back at a moments notice. I found that when I started telling people what was going on and asking for help, people came out of the wood work to help me no questions asked. Best of luck
