Has anyone been through this?

I’m ready for a change. I want to stop cussing, I want to control my anger, I want to start listening to more Christian music, I want to lose weight after my baby & I want to start reading more inspiring books. I feel like my relationship with my husband is going down hill because of the way I am. I will admit I cuss too much, I get mad over small things. It’s not always me, it’s him as well. I just feel like if I change the way I am to being a better me I would be so much happier in my life. Not just for me, but my family. Has anyone been through a change like this? How has it affected you, are you more happy? Was it hard?
