Adam Clarke on Psalms 39:2

I held any peace, even from good - "I ceased from the words of the law," says the Chaldee. I spoke nothing, either good or bad. I did not even defend myself.

My sorrow was stirred - My afflictions increased, and I had an exacerbation of pain. It is a hard thing to be denied the benefit of complaint in sufferings, as it has a tendency to relieve the mind, and indeed, in some sort, to call off the attention from the place of actual suffering: and yet undue and extravagant complaining enervates the mind, so that it becomes a double prey to its sufferings. On both sides there are extremes: David seems to have steered clear of them on the right hand and on the left.
