Honouring your parents

Hi everyone! I hope this is the right subreddit to ask this.

I (f20) have had a very rocky relationship with both of my parents ever since they got divorced 12 years ago. My mother is an alcoholic with severe mental health issues (diagnosed depression, possibly also borderline personality disorder) and my father does not like me a lot and never put in a lot of effort to be present in my life. I have not had a proper conversation with either of them since I was 15 and moved out when I was 17. Because of my unstable homelife growing up, I also had mental health issues for most of my childhood which I have worked on now, but they affected me badly for most of my life. I moved countries 1.5 years ago and have not been in contact with my parents since.

I wasn’t Christian growing up and neither are my parents, I found my way to Christ last year through a friend so I am still learning. One of the things that the bible teaches is honouring your parents and I simply do not know how to do that. I don’t want to ever be in contact with them again because of the way they are and their predictable behaviour- every single time I have forgiven my parents for the things they have done or said to me (which I do not want to further get into), they used my forgiveness and ended up hurting me more. I love my parents and I pray for them but I also worked so hard on repairing my mental health and building a life of my own and I know for a fact that it would not be good for me to start talking to them again. What would your be advice be for me on how to deal with this situation?
