One thing you can do to maintain your happiness is to form a study group. This will accomplish two things. First, you will bring your struggle out of the darkness if you have felt alone in your depression.
Second, you can support each other in your efforts to keep the focus positive and find the gifts of your depression. Listening to your pain while accepting your happiness is not an easy path to stay on, and the people in your support group can help you by providing feedback if you go too far in one direction or another. Others can point out if you are not listening to your pain, or if you are not giving yourself full permission to experience the happiness of healing your life.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
