I have been in a similar position before. It really helped my mental health to have productive daily rituals. For example, I spent about one hour each day between exercise and duolingo. Just get out of the apartment and run like hell. Even if the remainder of the day was demoralizing, I at least felt like something meaningful was accomplished.
Like others have said, find any job, contact family and explain situation, etc.
If I absolutely had no other option, I would join the air force. Worst part is the minimum four year commitment. A few of my friends have done so. You can be an equipment technician in a hospital, see the world, and not deal with any violence.
