I looked for words the last few days but can't find the good ones..
You are so kind, I wish I were a bit like you sometimes.
I'll keep good memories too, even thought it kills me to think about it.
I feel so angry with myself to hurt you, you don't deserve that pain, you did/do only good.
You delete me from facebook, if it's because you are angry I understand. if it's because you want to forget me I understand too.
But If later you manage to forgive me, feel free to add me, I'd be glad to help you whatsoever and have news.
You are skilled, amazingly kind, beautiful, speak well English, still have lot of time to complete your life (yes you have!), and great people around you, believe in yourself too.
Im thinking about many ways to finish this message but it's too painful.
"take care" is great actually
