I lost one to retirement many years ago. I considered her my friend and ally; the grief and sorrow were rough. I've even been reminded again recently with loss that it makes it the time to take extra special care of self right now.
It sounds like you are doing exactly what you need to be doing, they may just be concerned. During the transition, she reminded me that the new person, though trained, would not know me yet even if they had her notes. Continue to present things honestly, precisely, and to be your own advocate, as always. It made for a smoother transition while trying to find the right fit and while struggling at the same time, not hiding it. I had to explain in more detail where I was coming from at that juncture so they had a clear picture. It adds to the frustration but beneficial in the end. She had given me 3 names for a referral; I interviewed all three; and the one has been a blessing ever since. Trust in his opinion and find who's right for you.
The loss is significant, hang in there! Hope you feel better soon!
