My step-dad was an alcoholic all through my childhood and I stuck around into adulthood to keep my mum and sister safe. I regret now not walking away earlier as neither have been thankful for the help I gave, not that I expect thanks but I put my life on hold to continue living in the house. I cant honestly say it was worth it, but thats my situation not yours. My breaking point was him being close to punching me in the face (less than an inch from my face) because I asked my sister for a chip. It was something that small and silly that I turned to my mum and said I’m done, as of this moment I’m done. It took another 6 months to get out but my mum left him and I started to live my life. I just want you to know that one day that escape will happen and this will be over, you will start to heal and it will take time but it can happen!
