We are very uncomfortable with grief, our own and others. We sometimes feel we shouldn't grieve or that we should (notice the "shoulds"- they are not helpful) be able to get over our loss in a short while. We don't know what to say to others who are grieving. Instead of simply giving people the gift of our presence and the gift of grieving with them as we are instructed to do (Romans 12:15), we offer them Christian platitudes. We mean well, but we need to ask, "Why am I so uncomfortable with grief?"
Are you afraid that you'll begin to succumb to the victim mentality? Do you think that by allowing yourself to grieve you will be giving the thing you lost power over you?
Grief is a gift that helps you heal. If you short circuit the process, if you minimize your loss- regardless of the type of loss (loss of job, health, the death of a loved one, loss of opportunity, etc.), you won't heal. Unhealed pain can turn into anger or unremitting sadness.
It takes courage to grieve. It takes time to grieve. Ask the Holy Spirit to help you embrace the full extent of your pain. When you do this, you will find that He will meet you in it. Then, in time and with His help, you will begin to heal.
