I'm sorry you're here Mike...and I totally feel you. My strength that kept me going during my dark times a few mths back were my kids. Find strength in your S, focus on being the best dad you can ever be. And do try to list down some GAL activities that you can do.
Also the other thing that I do when I'm feeling down is to read the success stories in here. It keeps me going and fills me with hope again.
