I only just told my boyfriend of 3 years yesterday. We tell each other everything, but this was something that I was scared would push him away. Thankfully it brought him closer to me and he wants to work hard with me to understand this condition and help me through it other than that, I tell no one. The reason being: a few years back I opened up to my best friend about my self harm and depression, and suddenly she started self harming and was "depressed" too, and I had to start looking after her instead of myself. Is there a name for what she did?
