I can't tell you why you don't enjoy programming anymore, perhaps you're more interested in other things in your life than solving problems? (because that is what programming is, at least in my experience, languages are "just added flavor")

I've had times when I don't feel that I'm enjoying programming, followed by times when I'm really into it, there was this talk called "The Art of Code" that might interest you, the presenter Dylan Beattie shows what I now think is what makes programming interesting, it's about doing things, the programming is the how, not the what
