Hi @LastAirBender, welcome to the group.
Some people know from very early on what they want to do and find things they like doing. Some of us take longer to figure these things out. I won't say how old I was when I left my parents house... it's embarrassing and depressing, lets just say it was a long time.
Sometimes we just find ourselves in a hole and can't find our way out and so we convince ourselves that we belong in this hole. It's never true but it becomes so hard to see a way out. So you've made a great start by reaching out and asking for advice. That also took me far too long. So you're not a 'useless being', just someone in a bit of a hold and struggling to find a way out. Someone who is brave and strong enough to put their hand up and say "I need some help".
The trick is we want to try to make these big changes all at once and try to fix everything right away. It mostly doesn't work that way. It can take time. Identify some of the things you most want to change, decide which ones seem like the best starting points and focus on them. Start making small changes. There may be backward steps along the way, but that's normal. Concentrate on the small wins, and bigger wins will come.
From what you've written, some things might be getting some driving lessons, even if it's just from family and/or friends. Looking at doing some study. Finding something you do enjoy doing... this may take a lot of exploration and experimenting. Is there anything, even small things, you have enjoyed or were interested in in the past?
There are free resources out there can could help you with these. Or even support groups like this one where you can get advice and ideas from. You sound like you're still young. There is plenty of time to sort this stuff out. I know it's hard but try not to compare yourself to others. Doing so wont help and will probably just make things harder.
I has a similar problem earlier in the year. I got so depressed, I lost all motivation to do anything at all. I already knew the things I enjoyed doing but couldn't find any motivation to do them at all. When we're in a bad mental state, motivation can be a massive issue! So even speaking to someone about this, like a crisis line as already suggested, may be a great help for you to start to try to find some direction. It may not take much before you start to feel some motivation starting to appear to drive you forward some more. But like I said, it may take a lot of small steps rather than a couple of large ones. It does take time so don't give up and you'll make it. We're here to listen and help however we can. Just keep letting us know how you're getting on.
