It’s really hard for me to say if change is possible. Research says yes if they are really willing to change, they have to change so much, cut out “friends” cut out places and things, it’s a huge life change for them. We have a child and that still hasn’t been enough for her to change, she lost our family for months and that still wasn’t enough. Please always remember this is never your fault, not sure if you have been blamed yet, but nothing you do will ever be the cause of their decisions. Best thing I ever did was carried on with my life and let her do her thing, unfortunately that has led to crack use now but I have found it easier to leave due to focusing on my life. I’m not saying for you to leave, that ultimately is your decision but the best thing for you, as that is what this is about, YOU, is focus on your life and your time and mental health. I ended up on anti depressants from my relationship with my addict ex, and the best thing I did was doing things for me and therapy, lots of it! You are so young with so much life ahead of you and so many experiences to enjoy xx
