From a friend
You are not alone, I promise. Even though it may feel as though you are and that no one could possibly understand the confusion and loneliness and fear, but they do and there are lots of us. You needn't feel any guilt or shame, you might not feel yourself right now but be confident that you will get better. Don't be afraid to ask for help or admit that you feel vulnerable, it's ok and you'll find there are so many people who have been there through the seemingly endless struggles and total despair but come out stronger at the other side.
Do not give up, even when your old self is just a tiny speck in the distance of your memory and the thought of feeling normal and happy seems completely out of reach. You will get there, be strong and don't lose hope... "Into every life a little rain must fall" but don't forget that you need the rain to see the rainbow.
I wish you all the best,
Love from A friend
