advice?

so for the past several months, i have started self harming. it started out just as scratching myself with sharp objects, and eventually evolved into cutting. my boyfriend knows about my self harm, and has been very supportive throughout the entire ordeal, and i know he will stick with me. but recently he's been telling me that i should tell my parents (im 16) but for me that would mean therapy, being treated more like a child, and getting made fun of and gossiped about among my aunts. so honestly i don't think i could tell, but i know it would be best for me if i did. and believe me this isn't easy to talk about, especially when there are so many people who could see this, which is one of the reasons im posting this anonymously. and if anyone has ever self harmed, or knows someone who has, or just has any advice, it would be really appreciated. and also, if anyone has any advice on how to stop, i would really appreciate that too.
