Your dad will not destroy your life. Theres so much life coming for you. I felt the same at your age but I waited and got stronger until one day I was old enough to start my own life. My past has affected me, how I view others, etc but I’ve had a decent life so far. Try planning for your future, keep that hope alive. The addiction is more than anything. Think of a time when you really really wanted something; food, phone, etc something youd have done anything to get, eg that chocolate bar keeps begging for me to eat it. Thats how they feel every day. Their mind is that frazzled that nothing else has any space anymore other than needs/wants for what they are addicted to. The one thing ive learnt is lots of people are addicted in some way, its just some addictions are more accepted than others. We use them to comfort us, to help us forget and for some reason some people need that 24/7 and the rest of us dont. It will get better for you, just dont give up. Allow the unhappiness in but keep an eye on your goals for your future.
