I am not sure what you want legal aid to do - if you have a month-to-month your landlord can end the tenancy with the appropriate notice period in most circumstances. You can contact landlord/tenant clinics in your area (google your city) but it doesn't sound like anything illegal has happened.
I am very sorry for your situation. Start checking with nonprofit social services organizations. Understandably many of them are stretched very thin right now but they will certainly do what they can. Counselors there also understand the best ways to navigate government social services agencies and may have some suggestions for you.
You can get free -preliminary- counsel from a hotline like that of the City Bar Justice Center, the Bar Association’s pro-bono arm. They are open Monday-Friday 9-1 pm, and Tuesday/Thursday afternoons from 4-7 (212-626-7383). The center offers counseling on immigration, contested divorce, cancer support, consumer bankruptcy, and assistance for the elderly and veterans.
Volunteer Lawyers for the Arts has a hotline, too (Monday-Friday 10-4, 212-319-ARTS ext.1). Specialty groups like the VLA focus on specific constituents, in the VLA’s case, the creative community. Lawyers have their pick of cases, which they take on pro-bono. Here’s where you can find help from assistance with contracts to litigation, forming a non-profit or figuring out the legal maze of rights and fair use.
