until we only are being held on to

How long? 
The Psalmist also said, "how long, O Lord?".
Every trial seems to grow and grow in intensity until I am only being held on to.  Then- poof!- it's over. 
I am holding on to the truth that one day this present trial will be finished and life will seem easier again.
Is this how a weed feels when it is being pulled out of the soil?  If so, pull the weeds out and plant me with Your completely faithful seed.  Grow me into fruitfulness.
