When I was doing a similar schedule, it was a failure of introspection, and a mounting number of unprocessed emotional issues, and unconfronted personal problems.
The way I got over it is that I have started realizing, confronting, communicating these issues. I "sat down with myself" daily just to think for 15 minutes, without any distraction like youtube. Communicated what I though were my problems to my partner, friends, parents, therapist, forums, LLM.
Over time, patterns emerged, either by others pointing them out to me, or them occurring to myself. The patterns became higher and higher level, and I had more and more power and agency to fill in my gaps, and those in turn made my problems smaller, manageable. Challenges, even.
I also picked up hobbies that nurture the specific parts that I was lacking. For example, I had a very hard time to persistently care about living things. But after a leap of faith I successfully kept a plant alive, and I slowly build a hobby around this.
Funnily enough, youtube helped in this, because I also shaped that so that the helpful videos remained. While doing chores, self-care and other such things, I listened to a lot of mental health, lifestyle, introspective, hobby content, and these were wonderful sources of inspiration.
In a way, having a bluetooth headphone also helped a lot. It helped to bridge the gap between the digital world, which was my only comfort zone, and the "irl", which was like the cold, hard, overwhelming rest of the world that I didn't really want to deal with.
