Diesel, I'm sorry you're hurting, and I hope your heart grows less heavy over time. But it's a very painful thing. You must find a support structure of some type whether it be close family, friends or someone else you can trust. Granted family is not always ideal, and some friends can't handle it.
I had a small child who demanded constant attention, so I was able to transfer a lot of my anxiety into work. But I did have parents close by who helped, but I wouldn't call them true support. I had close friends and friends whom I thought were close. But I discovered that some of them didn't want to "catch" what I had. Of course, some former girl friends looked at me in distrust thinking I was after their man. Hoo boy. Fun days.
I hope you find your comfort place soon and get on with things as they should be.
