OH YES. very weird. every time i meet a stranger who tells me a life story i immediately call someone (sister, friend, boyfriend...) and laugh about it.
i'm sorry to be mean, but for some reason, people in our society are private. people dont generally tell personal things or stories so casually, unless they are asked, or unless you're trying to get to know one another (like on a date).
i hate to tell you to change yourself, b/c being who you are is whats going to attract the right friends and significant other for YOU. so i say... don't change. just censor a bit. open up slowly. like... make a point in not saying a specific story until the 3rd or so time you've hung out with someone....
