Poorly choisya

Arrendene

Hi all
I am wondering if anyone can give me some advice about my poorly choisya please? It must be six or seven years old possibly older and I grew it from a cutting taken from where I used to work. 

This year it’s looking decidedly unwell and I’m not sure what I should do with it, should I just leave it and see if it recovers by itself or does it require pruning? I would really like to save it if I can.

Many thanks in advance 😊

Did you keep it well watered last summer during the drought? It is very close to the wall and decking, I wonder if it goes a bit short of water.

If it's 'Sundance' (the golden leaved kind) I think they always seem to do a bit better with a little shade. They often look frazzled planted in hot sunny places - you see it a lot in people's front gardens.
