I'm a pathetic 24yo living at home.
That's a harsh way to talk about yourself. Why do you feel this way?
I don't have the money to travel and have fun or get my own place. I just sleep, eat and play silly games with my friends from time to time.
You need to make some changes. Either go to college or start training for a job. You'll never move forward sleeping, eating, and playing video games with your friends.
It's fine. I'll just keep feeling like a loser because of all those things you said.
It seems like you are unhappy with your life right now. You need to actively work toward making changes by trying to get a job so you can have the money to move into your own place. If you are unable to find the motivation to do that, you should talk to a mental health professional so they can help talk you through this issue.
