for people who self harm and are active in trying to recover, what do you do after the fact. I still live with my family and I don't know what to do. I have a plethora of other shit wrong with me so I'm trying to be honest with them, my family and I have a very strained history and our current relationships are not the best but we're working to change. anyway because of that and my other problems I have lots of trouble communicating and expressing myself. 
I was in treatment centers for so so long that I literally do not know how to tell people that aren't nurses how I'm feeling and that I've self harmed. in clinics it was all super structured and you'd tell them, give them whatever you self harmed with, have your wounds treated and then if you wanted you could talk about it. now that I live at home I just don't know what to do and how the logistics of telling my parents I self harmed work. I feel so much shame around it and haven't worn anything short, even in my own home, in years. 
I just really would like someone to maybe explain how they do it or give advice. I always hear about people who got stitches and I just can't wrap my head around that in a non clinic setting. I've had wound requiring stitches but I just left them, what do other people do who get them treated?
this was awful and long and badly explained but I feel like shit and need advice. 
TL;DR: how do I tell my family that I have self harmed so I can potentially have my wounds treated?
