Does POTS affect your work?

Hi everybody! I’m almost there on my diagnosis for POTS and also about to graduate college and I’ve been worried lately about my career. I’m in school to become a Respiratory Therapist and I’m really interested in floor care, but I feel like over time my symptoms make it hard for me to finish a 12 hour clinical day while in school right now. I just wanna ask to see if anyone works in any jobs that require you to be on your feet and how do you manage it? Is there something that I can integrate in work to manage and still be able to do what I want or do I have to consider other options?
