happiness starts with yourself....despite having a happy family life or relationship, it always falls apart when one isn't happy with the person they are.
Unfortunately transition is often the end to one life and the beginning of another. The ending is usually hard and sad, but the beginning is also brilliant and freeing. Take the time to mourn what you have lost, and when you've finished, leave it in the past. Don't let your old life stop you from living your new one
Good luck!
