I can't imagine what I put my mother through for years as an addict. I'm so sorry. Addiction runs in my family and I always tugged on her strings with the fact that she left me when I was six because she couldn't be a mother and an alcoholic. She was clean by the time I was 14 and then I started the cycle at 20. If you can both make it through this awful time it will get better. I'm now 41 and started a family. I still struggle, but I've learned to help myself to try and get better.
At 25 its so hard - you still don't know who you are or what you want to do. She will figure it out I promise. Hang tough mom - you are doing great. Now that I'm a mom, it breaks my heart to hear your story. I fear that I will pass this on to them one day.
