It doesn't take long after losing a "friend" to figure out the relationship really wasn't so good for you. That little voice inside of you that kept gnawing at your conscience previously begins to comfort you with reminders that the problem is not yours. The guilt of loss is not a burden you need to bear. You can move on and be a better person because of it.
It doesn't take long after losing a "friend" to know that you can trust people again. The hurt and betrayal are only temporary, and you know you will continue to let others into your life because that's just who you are. Maybe you'll be a little more cautious. Maybe you'll watch from afar a little longer. Maybe you'll listen better than you had before to that little voice that tells you to run.
It doesn't take long after losing a "friend" to find yourself again. Mostly because you've been there before and you know you'll be there again. Life is full of people who use you to build themselves up by putting you down. You know that relationships that tear souls apart are meaningless and hollow. You are better than that.
It doesn't take long to recognize that loss is a part of life -- though it be friends, property, health, or hearing. Some things happen by no fault of your own. That's just the way it is. Some things are better lost than found. You can hold your head high, count the many blessings you have, and thank your God that you are who you are, and that is good.
And you can bear your burdens with grace and dignity and perseverance... sometimes with a little help from your friends.
