Nothing makes sense

It should have never happened, not to us, not to me! Life has taken a nasty turn, one day every thing is right, you make plans you have dreams and then ... what? Nothing? Where did it go?
We all make mistakes, I know, but how do you forgive? How do you continue on when the trust is gone, without trust then what do we have?
Logic and reasoning tells me what to do and what I must do to protect myself, but my heart says the opposite. Why is it then when it comes to the heart nothing makes sense? No one can tell me what to do or how to feel, so no one can judge what I chose to do!
