Ah yes, the classical ''life is a gift because we have pizza and videogames yay!''. First of all, how do they even know if OP likes Marvel or Disney or whatever comic stuff or anime? But that's redditors we talk about, they love to act like they-know-it-all, even the life of people they never met.
Second, yeah there's a lot of bullshit to watch and it's enjoyable when you watch it. But after? You'll forget it immediately, in one week you won't even remember anymore. Your mind be making up space for the unforgettable suffering and bad moments that will come ;). I said and I will say again: Good moments are few in number, they are superficial as intensity and won't last long. Bad moments instead are plenty, they are very intense and last a lot. So why should OP keep living for such a superficial reason as a stupid movie or an anime if the bad will prevail in a short time again?
They're normies who have no clue about how life works and have been sheltered all their life, they come on that subreddit and other similar to annoy the hell out of people with real problems, thinking that they're some kind of saints for repeating the same thoughtless phrases over and over again.
Man go post on mental health subreddits (and reddit in general) only if you wanna suffer lol.
