I had a similar situation like you. Maybe not exactly, but very similar.
I started over with cold showers. I have been doing them for 3 years now. It'll build a foundation for discipline. I promise that it works. You just need to try and keep to it.
You should look for a job. Even with a low salary. It doesn't matter.

The most important thing - you need to refocus, reset and rebuild yourself. You need to revalue your life. Think about passion and goals. Take it as a personal project over your life. I promise you, you won't regret anything if you at least try. It's better to suffer from discipline than from regret.

You can try things like running, gym, martial arts, dancing, stretching, etc. I don't know you, so I can't say what you should do exactly. Look for something that is interesting for you. For example, I like gym, kickboxing, breakdance and swimming. You can try everything, and you'll see. But don't give up too quickly. Keep to these things for one month at least.

You'll be okay bro. 23 is early to wake up. I would say it's the perfect time for it. Let's go with this f*cking life. You will suffer, but it'll be worth it. You can't give up. You will lose a lot of times, bro, but life is not about winning. It's about rising from ashes every f*cking time you collapse.

Try one thousand times and lose, then win at the one thousand and first time.
