you didn't break her
As others have said - it's normal, probably developmental - what happens here with us is, we get past it & I think 'phew' ....and then a couple of weeks, or maybe a month later...it's all on again
Also at around 9 months separation anxiety kicks in (or can become more of an issue)

So you can try -
- cuddling her for a bit longer after she drops off to sleep
- letting her self settle, maybe stay in the room with her until she drops off to sleep
- co-sleeping if it's an option? even just for a couple of nights to get some sleep.

I usually try anything & everything, eventually something works (eg right now we are co-sleeping but the other day she self-settled in her cot)- sorry that's not much help I know, but just know it's normal & will pass
