Is it normal to give someone all your deepest thoughts?

Well over maybe the last few months i was dealing with so many emotions and then it felt like one day I just didn't know how to feel anymore. So i started writing down in a diary everything and anything its not a life story, a bunch of questions some of it is happy some of it is sad and some just weird. I could possibly explain as if you thought right now of some of the things you don't want anyone to know and write them down and give it to someone. Even though its not good or bad I was so held back by it all. Some of the stuff I wrote I told people but not others and a big part of it I have never told anyone. Giving it to the person I gave it to was the scariest thing in my life and she is not my closest friend or best friend she was the one person I knew i could trust and trust whatever she may do with it. After I gave it to her I became happy like as in I still feel happy and its a fantastic feeling. I can now accept the person I am and be the person I want to be and not feel so many inhibitions or fears. Also I have came to know that because of what has happened since I gave it to her she was the completely right person to give it to.
