I gave up drinking. Now what?

2 years sober. I drank to mask my insecurity and depression: I liked the more confident me it brought out, I liked finding new pubs, new breweries, new places to enjoy a drink in. But now it's just me, and I just don't know how to fill that void. As I get older, I find I enjoy things less and less. I hear people saying how great everything is now that they're sober but, 2 years in, I just don't see it.

Does anyone have any suggestions?
