Hi! If you're in danger or in an abusive situation, you can first try to reach out to emergency shelters. They can sometimes offer you a bed for a few days or weeks (it's rare, but possible), like they do for women facing domestic violence or young people who had to leave home. I don't know exactly what your situation is, but these kinds of places can usually help connect you to organizations (NGOs) that offer transitional or even long-term housing. Just make sure to check how it works in your country, because I'm not from the US.
Also, basic idea — if it's safe and possible, you could ask a trusted friend or relative if you can stay with them for a while.
You mentioned you don't have money, why is that? Are you unable to work, or just don't have time right now? In France, we have things like the "Mission Locale" for young people, or temporary job agencies (interim) that help you get work quickly. If you're a student, there are usually social aids, like grants, housing support, even free mental health help. And even if you're not a student, you can still get some forms of support.
Oh and I almost forgot, some churches or religious groups also open their doors when people are in need. Don't hesitate to try that either :)
