Working a career that relies on a lot of mental power while undergoing chemotherapy is the pits.
As a therapist, I have to manage my own schedule and case files, perform therapy sessions, documentation, coordination, emails, reports, assessments, supervisions, and several other administrative tasks. And a therapy session with me is normally 50 minutes. That's 50 minutes of engaged interaction with children, teenagers and adults...all with a variety of diagnosis and needs.
I knew I wasn't a model employee that year. I forgot meetings, appointments, and even client's names!! Paperwork fell behind. In sessions, it took everything in me to stay awake sometimes, much less be completely present, professional and engaged. In between sessions, I stole moments on a couch or would splash water in my face.
I was very, very, VERY blessed to have a workplace that was understanding of what I needed, and was patient with me. I still managed to do right by my clients and everyone, but no one faulted me for not being on my A game.
I like to describe to chemo brain as trying to walk a fat lazy cat on a leash. It sometimes feels near impossible to get it to cooperate.
If you have a coworker who's taking chemotherapy, give them a hug today. Tell them they're doing great. It'll make their day, I promise.
