Hi Wingy. Totally sympathise. Asked my endo for a recommendation. A week later she got back and said she'd retired. He put me onto someone else. But she was on maternity leave for another week. I'm still waiting.
In the meantime I saw someone else my GP recommended. Smart guy but he couldn't help me.
Eventually I realised on my own that my depression was linked with hypos, particularly prolonged lows while asleep. Through huge effort (including a CGM) I have almost totally eliminated lows. Slowly I am returning back to my old self.
