I'm glad you're opening up about what you're going through. It doesn't fix everything overnight, but it is the first major step on the road to recovery. Digital detox definitely sounds like a good idea, especially as it'll help you to break your porn habits.

To be honest, the way you describe your burnout seems very close to depression. I'd echo what simbyotic has suggested, in that it's good to reach out for professional help. Support from family and friends is invaluable, but a therapist you feel comfortable with may help you connect the dots in a more complete way.

I hope you find the digital detox gives you a fresh perspective on how your life can move forward, and helps you start healthier habits. We may not know each other, but I felt empathy reading your story, and I wish you the best of luck with the next chapter.
