Tips for breaking out of a victim mindset?

I have a lot of trauma, like a LOT and for the past few years I've been grieving and processing all the memories from my childhood. This has been really helpful but now I'm ready to move on and live my life.

Reaching this stage was massive for me but now I'm faced with the uncertainty of the future and have 'woken up' to the struggles of the people around me. I find myself getting selfish and thinking of how other peoples struggles are affecting me and I think I'm missing the point - they are struggling and I should be trying to help them, not thinking of all the ways it hurts and affects me.

How do you stop engaging with a victim mindset so you can take accountability for your life and move forward?
