I am 25 and about to fall off my parents insurance. health conditions are preventing me from working right now. i cant pay for my own plan. options?

Medicaid: If you are low-income you will likely qualify for Medicaid. Because Medicaid reimburses doctors at a very low rate few doctors participate and those who do generally can only spend a few minutes per visit so they do not lose money, but it is better than nothing. See https://www.healthcare.gov/medicaid-chip/getting-medicaid-chip/ to see if you qualify and how to obtain coverage.
