I am sorry.

Everyone reacts to death differently. There is no right or wrong way to react to the loss of another person. Suicide can complicate things even more. So, I do not think you are a psychopath. You are doing fine. You are working your way through your feelings about this circumstance and hopefully you will be able to reconcile your emotions and the event.

Please do not second guess what you could or should have done. It will just cause you to take on blame and guilt that is not your place. You were not the only person in her life and you cannot be held solely responsible for her death. Depression is an illness like cancer and it carries a death toll like any other major disease.

I am not trying to be dimissive, I am just trying to say that you can mourn the loss of this person without taking onnthe responsibility of her loss.
