I live with my mom and dad . These days I’m feeling a little distanced with my family especially with my dad. My dad drinks daily, he comes home after work, locks himself in his room and starts drinking for no reason. My mom never took a stand and stopped him. She has always cared about what other people will think about our family.
I hate my dad and I never loved him. I’m so frustrated living with them. I feel helpless and somewhere I’m afraid to stop such behavior of my dad because he starts abusing my mother and me when anyone says anything against him. I really don’t know what to do.

Maybe consider talking to your mom to tell her how you feel. Alcoholism is a disease. Your dad may need help. If your mom is in denial, she may need help to.
Possibly consider going to a social worker and getting them to intervene, or even someone from AA.
Hope this helps!

If he ever hits you or your mom, CALL 911! More people die from domestic abuse than anything these days. Talk to your school counselor too. You and your mom deserve better.
