To be honest, I'd never change things that happened around me that had impact on me, you never know if something worse could happen. The only thing I'd change would be making my mind and soul free, being more myself and doing things I like. No one is perfect so don't expect to be perfect as well. We all have our flaws we have to accept. Also, one thing I forgot is positivity. Great majority has problem with getting more positive. Positive thoughts are energy same as negative thoughts, it's about what we pick. My advice is to pick the first one, be positive in every situation you could. An old folk saying from my country is [roughly translated] how you radiate that's how you attract. I believe you can understand me.

Much love, have a great day!
