A 20yo striving to be better

Hi guys, I'm a 20yo from India, been into PMO for 6-8 years, I experience Depression, Anxiety and Cognitive dysfunction and memory impairment, Up till end of 2021 , I was a great student , I acheived academically a lot but after that everything came crumbling down and I realised that I've impaired my dopamine system, Thanks to Dr. Anna Lembke (if you don't know her, please search on YouTube, she is a goddess for me )....I wish to go on No PMO for 30 days as mentioned by Anna Lembke to restore my dopamine levels and after that eliminate pornography completely from my life and reduce frequency of MO to once or twice a month ( I don't have a partner and can't have one for atleast next 3-4 years as I've academic and family pressures ). Today was Day 2 on my streak and I relapsed twice, I'm going to start again from tomorrow, but I need some guidance on how to block porn and even pictures of Instagram models and any nudity from windows and android, I wish anyone can guide me on that.

Thankyou for reading my story
