I went through something really similar. I had joined Instagram as a way of meeting other photographers in the Bay Area, and had a great time shooting with lots of cool people, learning new tricks, and getting feedback. But the turning point for me was when I realized that the reaction (or lack thereof) to my photos could make me unhappy with a photo I had previously really liked. I decided I'd rather take photos to please myself than to please other people. Now, I shoot, and maintain a photo blog, but it's more or less disconnected from social media. I'm happy to receive critiques on my work, but now when I post a photo it's for me to look at later, rather than to get likes, and it's made me a lot happier.
