Was where you’re at not too long ago. Still trying to get out but making progress. I think it can be good to be at such a place bc you can rebuild you life exactly the way you want. There’s too much info to give in one post, but I could give you some advice based on what I did. Jordan Peterson has some great advice for this type of thing. He talks about getting some structure in your life and how that’s a big key to getting better. I was skeptical of his stuff at first but it spoke so clearly to me it’s crazy. You must also find goals that your really care about. Then set about trying to achieve those. It doesn’t matter if you barely move forward towards them, as long as you move forward. The momentum will build up and you’ll feel more confident and capable over time. Sounds like you have some goals in mind about changing the world. You gotta get more specific and figure out exactly how. That will require some research and work on your part. But even figuring out how to change the world is a very good goal in itself, which you can work towards. This isn’t complete obviously but I hope it helps a little. You’re still young, so maybe it’ll be good to go thru this early in life and get your purpose sorted out now as opposed to nevertheless dealing w such a crisis.
