One cannot avoid suffering. Our greatest Tzaddikim suffered (think of the Aseres Harugei Malchus). HOW we react to our suffering is what defines us. I know two women who both lost their first babies, R”L, but went on to have other children. One is very bitter for the last 30 plus years and takes it out on everyone around her. The other has dedicated her life to bringing happiness to others.
We suffer in life, we have joy in life (hopefully we recognize the joy). But it is up to us to deal with it in the best way we can. And sometimes we need help, in addition to davening and saying Tehillim and doing all the right things.
