I'm not good at poetry but often times I find that some of my thoughts have a rhythmic quality to them. Many people enjoy writing poetry as it seems to have a calming effect to it. Try it some time, you may be surprised at the results. It Find someone you can confide in. If you don't have someone like this or don't feel comfortable with anyone you know, try seeing a counselor.
Most health insurance offers counseling services.
A counselor can be very beneficial as an outsider who will listen and help guide you through your grief. A word of note though, if you are uncomfortable with your counselor, but still need to talk, request a different counselor. Sometimes you just might not feel as comfortable with one counselor as another. Don't be afraid or ashamed to ask to see someone else. Counselors are professionals.
