Only told one.
So far I think 7 people know. Therapist, my parents, my siblings, Sam and Juli,who found out on their own, and a guy named Jake that I told. He was my best friend, and he seemed worried about me, so I told him. He then told my sister in an email that was about 756 paragraphs long, (figuratively, of course) saying how worried he was about me and stuff, which made me kinda mad because he didn't know my sister knew, he just told her. She just replied saying "Oh, it's just a phase, probably just a one time thing". Well I still cut about 7 months later. So, that's pretty much it.
