Re: Glad for or glad of/ about!
You can be glad for someone when you are happy that something nice has happened to them. However, in your context, I would say something like "I was glad to receive your last letter" or "Receiving your last letter made me very glad". In both those case, "happy" sounds a little more natural but there's nothing wrong with "glad".
