President Dieter F. Uchtdorf said in his talk The Love of God "God does not need us to love Him. But oh, how we need to love God!"
We all have been through trials in our life that have tested our faith. Oftentimes we ask God "Why me?". There needs to be a change in our attitude if we want to recognize Tender Mercies in our lives. God gives us trials to grow and become humble so that we, through his son Jesus Christ, can come closer to Him.
There are many feelings that can hold us back from this realization. We have to learn to forgive. When we hold grudges against others or against ourselves we are filling our lives with negativity. Negativity is a great shield if you don't want to receive promptings from the Spirit. Laman and Lemuel are prime examples of this (1 Nephi 17:44). I urge you to forgive others and forgive yourselves, if you don't you will drown yourself in negativity. Never did I say it is easy, it is hard, but oh is it worth it to love God for all that he has given you and all the people he has placed in your life.
I am no expert but there are many talks o-n Forgiveness.
