I felt just like this- mainly when I wasn't really sure what I wanted out of photography. Establishing what that is helped enormously.
Photography is such a broad church and in my case I just wanted it to be enjoyable on my terms- I really like the process of learning the cameras themselves, taking pictures that I personally like of the subjects that personally interest me. Sharing the pictures with other people has lost a lot of its importance to me. What's good by anyone else's standards isn't that relevant. It's the process, outings and editing that give me most satisfaction.
This is world's away from how I used to approach it- I used to keep up stock portfolios, enter (and occasionally win) competitions , get published, exhibit in galleries, share to be liked etc.. All of that is cool but it didn't actually make me very happy. In fact it almost killed my interest completely. Letting go of the goal orientated nature of it was the key to me actually enjoying photography again. And obviously it's totally different for every individual- having specific ambitions is what a lot of people find most rewarding. No right or wrong but I think if you figure out exactly what you would you like out of it you will be happiest, whether that's popularity, achieving goals or just going your own way.
