Hey Jon,
I know exactly how you feel, as I am there right now, I too think I have forgotten how to be happy and how it feels, I also often wonder if I ever was happy, or have I always been this way. It hurts when my boyfriend says to me that I am like this all the time, as he must just see me as a right miserable cow. But if you need a friend or a chat, then I am about, I have just joined todday and am looking for some friends and people who understand me insted of looking at me like I am some sort of nut,
take care
Hugs
