If you are disabled most certainly disability services would provide transportation to apointments. Are you enrolled in disability services? Do you receive disability?

I can find disability services for you. Many of my students will never drive (seizure disorders or other impairments), they get around on the bus and my area has terrible public transportation, next to none. But they walk quite far to get to main roads to get on a bus. Can you take a bus?

If you schedule one appointment a month, you still can't take uber or taxi? Once a month? Aren't you working part time and you don't pay rent. How do you do date then if you can't get around ?

What's your disability? I recall you said you have depression and anxiety. Do you have physical disability with limited mobility?

Call your doctor, the one that diagnose you with disability and ask how to get to appointments. Call your psychiatrist.

At some point your parents will be gone and what will you do? If you are disabled you still need to build independence: apply for subsidized housing and disability etc.

Help is there. You can get help
