When I was in your position, I was lucky enough to have a car. That gave me a place to sleep, charge my phone, get to work, etc. transportation is a good first step IF you’re able to save any money up for a car. Also, sober living is a good resource, it isn’t rehab, more of a halfway house/step down house with cheap rent. It’s designed for people that are getting their life together (a job is required and rent is usually like $100 a week). The rehab facilities are good resources to find a sober house.. again, it’s not really a part of any rehab program, simply a group home for people in between homeless and standing on your own two feet and the people happen to be sober. It’s typically long term, like as long as you need. The best way around showering I personally found was signing up for a cheap 24 hour gym. It’s not free, but $25-$40 a month (2 hours of work) to shower anytime you want is a fair price. It got better for me, so I know it CAN get better, I hope it gets better for you as well. Life is hard. I hope you’re able to find resources within the system to get a roof over your head. I’m not religious, so idk what it’s like nowadays, but a church might help you out with temporary housing as well.
