my self harm in the future.

So as you may know I am 16 and have been self harming for 5, nearly 6 years. But now I am 16, 17 in august I will be leaving my family home soon. I see this as a great thing so I can become a lot more independant and can have my own rules etc. But this can be a really bad thing; living in my house is not hard at all. - can be harder at other times but generaally not hard. But to the fact, I think moving out will also give me the fredom to self harm and not get the fear of my mum seeing or my siblings at all. I am not sure if any older people who self harm have had the same problem but if so is it a bad thing? Hopefully when I got onto college/ uni I won't self harm. I really wish I did stop but it can be something like an addiction. Once you start you cannot stop. I fear this, a lot. I explain to people I hate my arms, just not the fact they are fat but also cause everytime I see them I want to just cut them up. I don't have scars at all on my arms, well I do but not too noticeable, the majority being on my belly. I have also thought of my job when I'm older, if I do become a nurse and if a self harmer came into a+e or something and I have to stich them up what could I say? Would I get triggered? Would I be reminded of my past?....I'm just unsure about my future. I am very scared cause I hate the self harm, well I urge to do it, do it, feel worse afterwards, do it, feel even worse, heal, scars. Its a crap cycle. Has anyonre had the same thoughts? How do you cope? What would you say to me? Thank you for reading. Xx
