Is it normal my friend acts like a 7 year old
My best friend is starting to annoy me with the way she acts. She runs around pretending to be a fairy or singing cr*p about nothing or just genrally being hyper. It's really starting to affect our friendship, I want to talk about serious things, have fun and go out places with her but she insists on being a shy little lunatic. I can't just stop being her friend because once, she had a total breakdown because she thought she had upset me, she spent 3 hours crying because she didnt say hello to a guy running past us! I want her to change but she won't, none of my friends are normal, my family have always been crazy, my mum didn't properly look after me or care about my emotional issues, I was bullied at school and I just need somebody to talk to...
How can I change this?
