How To Approach My Dad.

Hello everyone. I’ve been a weed smoker on and off for the last year and a half. I would go a few months where I’m constantly hitting the cart 24/7 and I would quit and try to fight through the CHS but it would rly suck because i could barely ever eat and was constantly nauseous and anxious and a mess. However I would end up getting sober, until I got back into daily use, and the cycle of quitting and starting again happened again and now this is the longest its gone on. I’ve been smoking the cart daily since like the start of June basically and now its mid September. Im going a through spot in my relationship so my emotions are absolutely out of control and I really do think the lifestyle of constantly having to hit the cart and wake up at 5AM feeling nauseous until I start my day, i just need to quit. My dad and I are pretty close and he is very understanding, heck he smoked weed for like his whole life and just quit a year ago. He’s honestly the best person I go to when I’m struggling mentally so he has rly been helping my calm down but he still has no idea that another big factor to how i feel is my addiction. I’m just worried cuz i dont want him to worry more, or be disappointed, + we live with my grandma who i dont wanna disappoint. And the reason i feel like i need to go to my dad for this help is because I actually have a job and college and commitments that idk how i will get past while feeling the withdrawals and not having any advice. I’m also an 18M who just recently graduated highschool and started community college. I just rly need some advice on maybe just tips on how to quit and live your life with these awful symptoms for a few weeks and advice on how I can bring it up to my dad. I know it should be easy i’m just a VERY anxious person and overthink everything. I’m hope this can make sense to some people, i’m just feeling like shit and wanna make a change and I just need help. Thank you.
