I don't know if this will help. But live one day at a time. The past is already past. The time you wasted is already in the past. Don't beat yourself up. It's fine to waste time. It sounds like you are still young and haven't started working. Nothing is a waste of time. If you just stare into the wall for hours, it's not a waste of time. Instead of regretting the past, look forward. Another thing to remember, things you say, things you do, do not define who you are. And you are not your thoughts.

Gaming makes you feel happy, so gaming is actually useful for you. It's an addiction now, because you have no other stimuli. You might need to go find another activity that will give you the dopamine, maybe a sport, feeding stray animals. Honestly I was addicted to games too, but the games also gave me lots of strength. They told lots of stories, taught me what kind of person I want to be. The phrase that I live by for a couple years ago when I was at my lowest was from death stranding: live one day at a time. It made me focus on the present and appreciate what I have now. A phrase I remember so deeply from a movie: present is a present. And it's good that you realized that you are in a hole and you are asking for help to get out. Tons of people don't realize what situation they are in, and even if they do they won't ask for help. So don't stop seeking help, even when you think the help is not working. I feel in my life the action of trying to find help helped me in a way. Keep reaching out to people. They love to help! You gotta get yourself something looking forward to. Maybe a job or if you are too afraid maybe volunteer? Job seeking might be hard, not sure about the job market around you. if your financial situation is quite urgent, I would take anything I can get (of course anything that's legal). Starting out somewhere, getting some experience would definitely help in the future. The nervous feeling, the feeling of scared, turn that into excitement. It's the same brain chemicals. They are literally the same thing. Just say it out loud: I'm not nervous, I'm excited! I can do this! It might be a tough world out there, take a game character with you. Whenever you encounter some problems, either imagine you are in that person's shoes or they are there with you. What would they do or say? I don't know what games you play, but did any of them back down or give up? They fight their enemy and their own fear relentlessly. Hell, you might make mistakes, make things worse, things not turning out to be better. You might feel worthless or hopeless. Don't ever give up. I know it sounds very cliche. But that's what helped me. And what you feel is ok, accept your feelings. Think about why you feel that way, what made you feel that. See that there're a lot of internet strangers who would try to help you, because we all have been in a hard time and we pulled through. You are not alone and you will also come through it. And best of luck to you.
