I'm so sorry about your birthday =[ Feeling alone and unloved is one of the worst feelings. For me it's even hard to accept that God loves me when people around me aren't loving. You picked a safe place to vent your feelings, I will be praying for you!
I will pray that if God wills to lead you out of this lonely chapter of your life and into new adventures, that He will stretch you and give you courage to break out of your shell and be who He wants you to be.
And if He wills that you walk through this time a little while longer, I pray that His presense will be sweet and dear to you and that you find comfort in the knowledge of His love.
Hugs to you sister, bless you.
