I often feel such feelings. The reason I have found out for why I do so is due to lack of sleep. When I have lack of sleep I often look on the negative side of sides, often think no one likes me and I think everyone is saying bad things about me.
But when I have a good sleep I often change personalities completely and am a different person. Try to get a good amount of sleep each night (Atleast 8 - 9 hours) and remember, we all only live once. Don't look back.
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.
