I finally gave up years of hating my half sister
Thats great! When did you stop hating her?
I wished her a happy birthday a month a go.
I'm glad you finally got over that!  It's wrong to hate siblings, even if they're only half siblings.  Good for you, patching things up with her!
I feel great! I've been focused on trying to mend things with everyone lately. I made up with my ex, and I'm talking to a classmate that I never talked to before. I'm really moving forward in life.
Thats wonderful. Being at peace with yourself can really help you make progress in life. It gives you time to focus on things that are important.
