Hi and welcome Gloriosa.

From your initial summary of the situation, you come across as an intelligent, literate woman and my feeling is that yes you could do the job, it's only self-doubt that is holding you back. When I want to do something but am feeling out of my depth, I break it down and daft as it might seem, i pick up the phone and say 'yes' to whatever and don't think about the consequences. I f I do think I dither and talk my self out of it.

Splash has come up with a good idea about being able to split the job with someone else if you think that would help.

As for your Mum passing away, well all I can say is that when mine passed away, I spen 2 weeks felling miserable and then like you gave myself a good talking to and got on with things. It was the right approach for me, but not for eveyone. If it is the right way for you, I guess you would have made your mum very proud.

Good luck
