I’d say either or both. If you have a GP it might help to talk to them as well. While mental health may not be their field I’m sure they’d be willing to help.

I’m between GP’s at the moment and went to my neurologist. I was very upfront with him about my mental health reasons for taking time and they were my main concern. I do have a seizure disorder and had one ~3 weeks before my leave but made it clear that I believed it was stress induced due to my job and mental health status.

He disagreed about the stress being a factor in my seizure but said that if my mental health was as I depicted he had no issue authorizing my leave despite it not being his direct field. He set me up with a therapist in his hospital system for a ASAP sessions and i worked out a regular therapy schedule. My psychiatrist wasn’t much help and consistently tells me that he is medication management and not really about diagnosis, but more so for medicating a diagnosis from a psychologist. Really weird and a system I am working out of. Oddly enough my therapist and I have decided to reduce my medication to zero (not there yet) to help with some side effect overlap from my seizure meds.

Help is out there, seek it. It may seem daunting but it’s better than suffering in silence, I promise you.

ETA: my leave was officially designated by my neurologist for mental health reasons and as far as my work was concerned it was a medical leave.
