Homework / test Arabic to English Art/Literary Poetry & Literature Poem

I wanted to confirm that there can be several basic past forms to this verb, as it appears here.


أتشبّثُ بكلماتك
يا نزار
حتى لا أُجَنّ
حتى لا أنهار

I suppose it can come from either from جَنَّ or or even from أَجَنَّ (less so meaning-wise - "cover", "hide")?
If جَنَّ - I see that "fall" is an acceptable meaning.
Of course "go mad" is the first meaning the comes to mind, but I feel the register is not high enough. Can anyone think of one word that can fit and convey that meaning? That would be ideal.

Otherwise, this is what I suggest:

I cling onto your words
Nizar
Lest I shatter
Lest I collapse

I feel this keeps some of the rhythm and "shatter" is like "fall".

What are your thoughts?
