I'm sorry you're in such a tough jam. Every community is different. I don't know what Boston has to offer, by way of help. I'm thousands of miles away at the opposite corner of the country. I know, in my area, stag guys have the hardest time finding shelter. The shelters prioritize adults with children and women. A guy with a woman can get in some shelters that won't even take a guy alone. There's probably some sort of agency in the city (maybe more than one) that provides healthcare to the homeless. Boston and Mass, in general, is pretty active in matters of social welfare. Still . . . it's a big city, and I'm sure there's nowhere that's going to just set you up with a place to stay. But go to wherever provides healthcare to the homeless and ask to see someone for psych medication.

I recommend this whether or not you even want to be on medication. You may be taken a lot less seriously as needing support, if you're not being treated for a psych issue. "Being treated" tends to get interpreted as being on medication. So say you're depressed and get on something, if you aren't already. Then keep getting the prescription filled. Some agencies that help homeless people will check to see if you are "compliant with treatment" - meaning are you picking up your meds on a regular basis? (They call the pharmacy, or wherever you get your prescription filled, to see if you are picking up medication there.)

I'm sure Boston has various programs to get homeless men off the streets. But these type programs don't usually advertize on billboards. Sometimes you have to wait to be invited into a program that is run quietly. That could happen in various ways. Some shelters have more intensive help available for people who show up at the shelter who seem like they would be willing to commit to a program that makes demands of participants - like "no substance using." Try out as many different shelters as you can find. People working at, or running, some of those shelters may be "gate keepers" of programs that might help you. Show up, be cooperative and offer to be helpful in any way that they might like service from you. Check out Salvation Army shelters. Check out shelters run by other religious groups. Most aren't lookkng to convert you. They may sincerely want to be part of helping you find a longterm solution.

By now you know that other homeless men in Boston can be a source of information about what's available. Be nice to everyone you meet. You never know who might connect you with somerhing
