<human>: I know this problem of mine might come off as the very cliched "i have no clue who I am" dilemma but I actually have no clue as to who am I. So everytime I read a book, I can't help but copy the personality of the heroine or basically anyone who I think is attainable. 

Like for example, I've read a book about a girl who goes MIA, cut all her communications with her family and friends, cut her hair, buried her old journal and started again with life. I tried doing that as well that it came to the point that I ran away from home. My parents were worried sick. I also cut my hair short, bought a journal and filled it with random thoughts then buried it. That's just one of the many things I did. 

My boyfriend had already talked to me about this, saying that he can't keep up with me anymore and he just ends up confused whenever he's with me.

I feel like shit. I don't want to worry those people I care about anymore. But I can't just stop. If I stop, it's like I'll lose myself even though I think I already did since I just copy paste fictional characters on to myself. What should I do?

Give me a shortened version of the text
<bot>: i have no clue who i am so I just base my personality on fictional characters. Parents and boyfriend are already worried. What to do?
