Allowing oneself to feel sorrow or any other negative feeling (owning the sorrow) without judging that emotion is OK. This is what the tonglen slogan “Drive all blames into one, ” means. Sorrow and joy are opportunities for growth, and we should be thankful for both.
In his website, heaven4earth, Mario d’Elena has a post called, simply, “Thank You.” It expresses this very well.
