My answer to each:
1:I literally had 94 subs on my channel and like 4 watch hours. Your situation could be alot worse.
2: those people probably feel bad about their taste of music. They Probably listen to some kidz bop songs or some 7 year olds singing “my stupid heart” horribly.
3: talk to your family about getting a therapist, or just let your family be your therapist. My Dad once walked through nature when he was really stressed, and came back fine. Maybe take a walk in nature, and let the sounds and the beauty of it calm you.
