I had some absolutely miserable times, which your comment reminds me of, when I was in my 20's. I'm 65 now, and my two grown kids have come to stay with my wife and my for Christmas. We played a board game for hours last night, like when they were young, and had lots of laughter together... My point is that what you're going through will pass. It does take work; so keep up doing the things you know must be done to move your life ahead. You have received lots of good advice in this thread; I don't need to say more (except one thing I will add at the end). Do what you need to do, and this period will be over, and life will be good. My one piece of advice is that I've found meditation is very helpful. It enables me to let go of negative thinking that arises from painful times decades ago, when those thoughts do arise. It's a very important part of my life now.
