The idea of knowing what you want to do with your life is overrated. A lot of people do a lot of different things and often don't know what they're going to do until the inspiration hits them. In the meantime, do things you like. Don't make any big decisions without thinking about the implications. Try out new hobbies and activities and see if any of them feel like something you want to do more. Oftentimes one interest will drive you to a similar one.
Get a job if you need the basic stuff people need to survive. Preferably not a job that demands too much social masking if that sort of thing causes you anxiety. That may be hard to come by depending on your skill set though. You can look at people whose jobs you find interesting and ask them what they did to get there. But it may also just be a matter of finding a job you can tolerate so you're able to do the things you enjoy when you're not working.
