I think about my death almost daily.
Is it because of something from your past?
Yes, I think about the things I have done in the past.
There's nothing wrong with thinking about death sometimes, but if it consumes your thoughts so much that you're thinking about it daily then that's too much. Thinking about death that much will cause you to have a negative outlook on life. You should consider seeing a therapist so they can help improve your outlook on life.
Why? It's not like therapy will actually help?
It is worth a shot! You should not think about death almost every day. It is unhealthy.
