One thing about having a serious injury is that you're outside of normal life. It's easy to dissociate and become enveloped in the depressing painful world of your injury.
Visits from friends and family over the last few weeks have been very important to me. They make me feel connected to my real self and my real life.
If you have friends or family who are in the hospital or recovering at home, take time to visit. A 30 minute chit-chat may not seem like a lot to you, but it will to them.
