I have a very personal relationship with this feeling. I find myself feeling lost quite often. I look around seeing many people with someone in their life and I can only wonder what that feels like. You see I have spent the better part of my life alone. It is easy to feel lost when you are alone. You wonder of your purpose in life. You wonder if you are making a difference. At times you wonder if anyone even notices you.
I have come to find peace and my place in life by being grateful for the things God has given me. There are many things that give me joy and I turn to those during times when I feel lost and alone. These are gifts that God has given me to help me through these times.
You are never lost and alone because God is always with you if you let him into your heart.
