I feel like I know nothing about how to advocate for myself.

I was looking forward to my second physical therapy appointment on Tuesday. I put in notice as soon as I made the appointment to be off work that day at the dress shop... which they chose to completely ignore. They scheduled me on top of the appointment time so I had to decide whether to stay employed, even if it is a low-pay part-time job, or get the medical care I have trying to start for months. I cancelled the appointment and will try to reschedule it on Monday. Then I'll just hope that I'm able to be off work that day because RTO requests are nothing I can count on here and they ultimately do not give anyone a predictable schedule in retail. Woke up in a decent mood and now, after seeing the new schedule, I'm feeling defeated again. I still have too much pain to travel anywhere by car. No one wants to see me without insurance. No one wants to help me apply for Social Security or Medicare when I turn 65 in October. Meanwhile, EVERYONE is sending me invitations to buy medicare or social security "services" from them .
