Should we dwell on problems or pick ourself up and get on with life?

We all have problems in life. I've been through all sorts of things as many of you have. I was trying to go through some of it last night to explain to someone...childhood molestation, rape, groping, physical/spiritual/mental abuse, not being protected etc etc. When I was younger, I wanted to hold onto it because letting it go felt like I was denying myself the justice I deserved but never got. I still sometimes slide but as life goes on you realize that you spent it in misery, not fully participating in life entirely...that time is gone forever. So idk that might just make someone angry but that's part of my story. Take care. Much love.
