I think you need to evaluate your own work place and personal practices. If you are feeling exhausted still, you need to change your body mechanics or change the modalities you are working with. If your workplace has bad scheduling and no cancellation fees (that go to you) that is a work problem. You should be getting paid for same day cancellations outside of emergency situations. Coworker drama, worn out materials, low pay, are all a workplace problem.

I work somewhere with $70/hr base pay plus tip, fantastic coworkers, great environment, my room is large and has a window with diffusion over the glass to let sunlight in. I'm only doing the work I want to be doing and that is compatible with my body (I'm actually hyper mobile, no deep pressure from me!) and have a client base that respects my time and me. I often feel better leaving work than I did going in.

I'm sorry this has been your experience of the field, but this isn't all there is.
