I'm told by both relatives and a psychologist that I gotta

Because people who consider themselves your betters like to impose their values on you. Or because you won't stand up for yourself.

Because, like denying a child cookies for dinner, they love you and can see far reaching consequences where you cannot.

Nothing is wrong with relaxing with video games and anime. There is something wrong if all you do is relax. Those things are a life destroying trap for many, many people.

Don't try to make yourself out to be a victim because people who love you are expressing concern for your well being.

If you are 100% satisfied with your life right now and will never regret how you're spending your time, then keep on doing what you're doing. I don't think that's true though since you're already seeing a psychologist. These people probably see you reaching a point where you look back and say "Man, I wasted a lot of my life doing pointless shit when I could have been doing something else." So, it's up to you what you want out of life. Just don't deny yourself enriching experiences just because you want to spite people with different opinions.

Video games and anime are not understood by the older generation. They think these are hobbies only young kids have and adults should be watching sports, sitting at a bar and doing other "adult" things that they perceive as more meaningful.

"Something meaningful" what the hell does that even mean? How do you decide what's meaningful and what's not? Is there a way to quantify it that I'm not aware of?

If that's all your psychologist said regarding this issue then he's a clueless moron and you should stop giving him money because he's giving you the same kind of bullshit cliche advice you'd hear here. If you had something meaningful to do you would've done it without someone telling you to. That's not how it works, people don't just go outside and find meaningful shit. Nobody even knows what the fuck that is, but you're supposed to find it and do it, otherwise you're some depressed looser, even if you don't know it.

There are people who are depressed and blame it on spending all their life playing games and watching cartoons. And there are people who are depressed despise always trying to "get out of their shell" and do "something meaningful". If you're happy with what you're doing now and it's not making you sick or poor then keep doing it until you're not happy with it anymore. Everybody think they know the way to live and the secret to happiness and they will try to convince you of it. Some will even ask money for it. Stick to what works for you. If you feel the need for a change then by all means do it. But don't do it just because a bunch of people are telling you to. Your experience is not an objective thing they can measure and understand, they will never know it better than yourself. They can only guess, but they will do so while being convinced that they know what's better for you. Whatever the fuck that means. They don't know what's better for you. They don't know what you want, what makes you happy, what makes you sad, what gives you pleasure, what puts you in a good mood. Most likely you don't know either, people usually don't know themselves that well. But you sure as hell won't find out listening to other people.

fuck im, if you're content with what you are doing tell them to fuck off, i make my own decisions
