My mind is broken. Maybe Nofap helps.

I'm happy that you realized that you don't want to end up in that dark place. My advice would be to go with small goals first. For example, try 1 day without porn. Then try two days. Then try avoiding porn for 3 days straight.

 

It is true that sex addiction can lead you to a very dark place, but don't worry, you have realized this problem before it's too late, so now you can start doing something about it. I would share a few things that worked for me:

• Plan your day with timetable, in the morning, write down 2~3 tasks that you must finish today. (there's no need to be a perfectionist, just try your best to stick to it)
• Meditation (I use the Seven-point meditation posture, and do it right after getting up before I get off my bed every morning)
• Write a short passage to repent for your past mistakes, and write a few words on why you want to go NoFap. Read it every morning to remind yourself what kind of person you want to become.
• Don't forget about NoFap, study NoFap materials / visit this forum every single day, make it a habit. (If you are not motivated on that day, just spend 10 minutes, don't push yourself too hard)

It is not easy to go NoFap, it takes time and dedication, but I can guarantee it would be worth it.
