The song is "Outta My Mind" by Anthem Lights. Here are the lyrics followed by a you-tube video.
"Outta My Mind"
This evening we are going to dinner with friends of ours to celebrate birthdays. I love these people like family and they are some of the best friends Jonathan has and he considers them family. However, I am really nervous about going. There will be 2 babies there. 1 is a one year old little girl that I have seen multiple times. One is a new baby boy who was born the day before Grant's memorial service. We prayed for this couple to have this baby (they had infertility too), and he was born premature while his mommy was really sick. However, I had dreams that their son and our son would grow up being friends (just like their daddies). I'm scared that I'm going to break down and lose it in front of everyone. I think I will have to have this song and a few others on repeat in my head.
