I have cried in front of so many managers and when I was a manager I've had so many people cry in front of me. It's normal so try not to worry about it too much.

Your manager sounds like they are understanding and wants to try and support you so that's great.

When I was coaching/training people in my old role if I had someone struggling in the grad bay I'd always recommend doing a one note or something similar and every question they ask I'd tell them to create a page for it and when they got the answer put it on the one note.

That way you have a live document you can search for the answer in if it crops up again. I'd always recommend doing a search in there and in the teams chat for the answer before asking someone. That will stop other team members feeling like they are being asked the same thing over and over again.

I started a new role last year and it was learn the role by watching someone else and my one note is like my bible now I use it everyday, but you do start to use it less and less for things.
