The theme of Lamentations 2 is the anger of God. There were a lot of things going on at that time that made God angry. I think there are a lot of things going on in our world today that would make God angry. That's not surprising. The rest of the chapter gives us 3 responses to God. 1)Cry. Crying is a good, healthy, appropriate response. 2)The inappropriate response is that there are people who are giving others false hope. We see this today as well. Some people tell us everything is going to be fine when its not based on any facts or reality. Don't listen to false hope. 3)Cry out to God in prayer. The appropriate response is to turn to God, to honestly express your feelings, and lift your prayers to Him.
