I'm so impressed with you based on your question. It shows great insight, compassion, and desire to move forward with your life. So many of us (myself included) get stuck in the blame game, keep recycling our past, and don't enjoy the here-and-now. Since you already understand your dad was emotionally absent and why, you're doing great and are ready for the next step to jump-start a happy future.
My 80-year-old mother was recently reminiscing about her mom who died from alcoholism and said, “She chose booze over me.” I was immediately struck my how tragic (and untrue) that comment was and how my mom had no understanding of addiction and depression. I knew this ill-conceived belief of hers had negatively shaped her life and the lives of my siblings and me. I wished she had attended Al-Anon meetings, read books about alcoholism, and gone to therapy before getting married and having children. It would have saved us all a lot of heartache.
I hope you will avail yourself of the resources my mother didn't. By putting in the effort now, you'll have a happier life in the future. By talking with others, you'll realize you're not alone, find camaraderie in your shared pain, and learn how others have moved forward. There are so many of us women who identify as fatherless (I in 3), and 10 percent of U.S. adults say they grew up with an alcohol-abusing parent. Janet Woititz wrote Adult Children of Alcoholics, an excellent book in which she discusses the common traits that people with alcoholic parents share.
I found a lot of relief, support, and peace of mind by being vulnerable and sharing my experiences as a fatherless daughter. When you open up and reveal your pain, you meet so many people who will do the same, and an instant connection is formed. For too long, I lived a life where I seemed strong and put together. In reality, though, I was numbing my emotions by taking anti-depressants. The seven years I remained on those were the worst of my life, “my lost years,” because I lived like a zombie. While I felt no pain and never cried, I also felt no joy. My doctor did me a great disservice by prescribing drugs to me instead of urging me to do the hard work needed to get better. I do that now: meditating, writing in a journal, focusing on gratitude, spending time in nature, exercising, eating healthy foods and, most importantly, dealing with my feelings instead of stuffing them.
I wish you the very best as you move forward. I think you will have a lot to offer those who are on a similar journey.
