I want you to learn from my mistake,

and NEVER let yourself be in a position where you invite someone to victimize you. There are things and situations we can’t control, but if you do everything in your power to avoid coming across as a victim (either externally or internally – the power of thought is not to be under-rated), then you are not only less likely to actually become a victim, but you’re less likely to FEEL like a victim if something happens.
Go read. Now. And pass it along.
