Totally off subject

I'm a 16 year old girl and ever since I was like 5 I've always like talked to myself, But more as in be different people AND myself. partly cause I didn't have friends when I was little so I'd have imaginary ones but I've not actually grown out of it. Anyway my mum walked in my room while I was talking to myself and I kicked off and later i heard her say to my dad that I was a weirdo and he said only reason I talk to myself is cause nobody else will listen. is it weird that I do this though at 16??
