Here is famous ted talk about fatherhood https://youtu.be/RlSwsE22nX0

I myself was raised by mom alone, my mom was a housewife, she did her level best to raise my sisters and me. I have to say she was the best mother in the world. My dad was working abroad till i became 21 years old. Because of lack of dads care (he also was a alcohol addict), I also started using drugs when i went to collage and I went literally crazy two times. Both times i almost faced death due to drugs overdose. I became drug addict due to lack of social skill and low self esteem. It is really very hard to grow up without father even after having a caring mom. I think my father became a alcohol addict because of pain of staying away from family, as i could feel the pain in his eyes when he used to visit us yearly. Its not only the boys who suffer from lack of fatherhood, One of my sister was suffering from depression for long time, Now I am drug and alcohol free.
