I think most YMCAs do have financial assistance. I checked into the one we go to and the financial assistance was a sliding scale and based on Federal Poverty Levels. With some assistance levels, a certain number of volunteer hours were required, but I think the max was 40 hours per year, which isn't really much when you are getting a free membership. The YMCA we go requires an application, taxes (or pay stubs), a letter explaining how the 'scholarship' will help, and an 'interview'. They can probably help you with what to bring sSince you didn't file taxes last year due to no income.
I don't know if all YMCAs are the same in terms of financial assistance, but it's worth looking into. I would go there in person if you can b/c it's easy to not respond (or forget to respond) to an email or phone call, but harder when the person is standing right in front of you.
I recently changed my username, but I still say "Hello" to all those who know me in real life! Hi P, S, T and K!
