Maybe Medicaid in your state

Contact the National MS Society. They have different resources that may help. Also, there are foundations that help with expenses. https://www.patientadvocate.org/ is one, https://tafcares.org/ is another. Hope this helps.

Are you able to apply for disability? From your state and possibly also from Social Security?
That will need a doctor who says that you are disabled. If you don't already have doctor who says you are disabled I believe they have you see a doctor (they pay for it) and get his recommendation. But call them and ask about all of this. I am not sure about any of it and just my 2 cents worth.
Are you eligible for Medicaid? I would suggest that you apply for all of those and check with your local city and your county for whatever assistance they have available. I wish you all the best!!

There are many resources for someone in your position. Things may take time. Hopefully you're in a better position since it's been a few months. There is always the MS society as someone has suggested already. Also, where do you go see your neurologist? Hospitals and clinics have social workers that can help guide you in applying for all sorts of local and state resources. Would you be able to work remotely from home? I'm around your area at least once a month if you ever want to talk. I know I found it helpful to meet other people with MS.

Also, I have medicaid. Everything is covered. I pay nothing out of pocket. Again, I don’t know what New York has, but in Washington it's called Apple health.
