This is not to minimize your sense of loss, but the truth of the matter is that you're still here, and life must go on. In fact, it will go on regardless of whether you catch the train out of the station or not.
Now is the time to take the opportunity to revisit old interests, develop new hobbies, strengthen old friendships, cultivate new acquanintances, etc. Your life has taken a different turn than you expected, but with God's help you can make it work and still experience all of the richness of life that He offers despite the fact that your loved one has gone on.
Keep your mind occupied. Keep your spirit occupied. Keep your body occupied. Everyone grieves in a different way, but the common denominator of the human experience is that left to its own devices to dwell on itself the mind can take you to dark places that are in no way beneficial to your wellbeing.
Be careful to continue to watch your personal hygiene. Be vigilant against allowing your home to become cluttered and lacking in your care. Don't allow the television to become your best friend. Diligently handle the business of your household.
Move at your own pace, but move nonetheless. Remember, stagnant water becomes putrid, and this is not the way that you want to honor the life that you and your companion had together.
Remember the good times. Pull out photographs that reflect the experiences that you had together. Welcome the opportunity to discuss him with people who knew him well. Read your Bible and allow God to do His work behind the scenes to heal you and bring you through.
Take the first steps into your new life. You've only just begun ...
