Change can be difficult. Unexpected change can be incredibly difficult. Like losing a loved one or a job or a home. Life sometimes pushes us into unfamiliar territory and we're all of a sudden faced with the option to sink or to swim.
No one expects you to hop into what feels like another persons life immediately and take the world by storm after being knocked out of normality, but you owe it to yourself to not allow life's circumstances to totally stagnate you. After dealing with the initial shock of a thing, the next step is to accept it. Easier said than done but possible. The act of stepping isn't just related to active movement but to our emotional and mental life as well. If acceptance has been hard for you, surround yourself with those who know you and who can offer wise counsel to help stir you back to solid ground.
