At some point you will be challenged if you are seen to be slacking off from what you used to do.
Before this happens,the best thing to do is approach a sympathetic Elder and ask advice on how to deal with your mounting (fake) depression.
You will get the usual bollocks about "do more study" "do more F.S" etc. Simply thank him, and carry on fading, a bit at a time. If another Elder asks you about things, say dear Bro Sym-Pathetic is lovingly helping me.
If Sympo comes back to you, say you are really trying with what he said, but finding things difficult, " but the other Elders are being helpful too ".
When they discuss you, each will praise the other Elder for what they are doing, divide and rule !
Fade some more. If you are really pressured you will have to fake severe depression with suicidal tendencies, then say, preferably in a letter, " please leave me to recover from this, I will be in touch just as soon as I need you." Of course you will have to fool your JW family too.
It can work.
