It's been a few days, but here goes. I'm a 25/M if it matters.
It's important to find strength in yourself to take the first step, I'm practically neet as well but work with my mother and it always feels like the work I do is inadequate, but over time I've seen most people really appreciate it. There are some who will always try to wring every dollar they can by complaining, but we generally give them a much higher price and stand firm on it; they don't deserve better. Working with your family could be the least stressful thing you can do, since they can understand your situation and cover for you, and you won't be discriminated against while being hired. Even if you end up not liking the work, you can have some experience from it.
There's nothing wrong with having hobbies either, singing or learning a language doesn't have to be for anyone else or for money; enjoying it and bettering yourself is enough. I was learning Japanese too but realized I'd only ever use it to read manga, so its on the back burner for me.
If you feel like you're in a rut, you could try figuring out some welfare programs or claim disability to get some form of income; if it really comes down to it, you can go to the welfare office and apply for unemployment, the social workers usually ask you to submit 1 application a week in america and can give advice if you do want a job. When I started working with my parents, having just a few hundred dollars a month gave me more confidence to go out and not get stranded somewhere. I don't have a car or license, but there are stores I can walk to and just pick out things. Having a healthy diet and/or taking a multivitamin, as well as moderate exercise, can also help improve your mood a lot. The most important thing is to not think its hopeless, any situation can be improved, but change has to start from within.
Also you probably know, but most people trying to get your email are likely feds or worse. Hope it helps.
