It's very interesting that so many posters have suggested depression (or other mental afflictions) as the culprit of the OP's present disinterest in guns. While it's seldom a bad idea to visit the family doctor and get checked out, I'm hesitant to diagnose this as depression. I've felt real depression, and it's more dynamic than just losing interest in hobbies. To me, this sounds like simple burnout--getting tired of something from doing it too long or focusing on it too much. I can sympathize. A lot of of gun owners (myself included) can be compulsive about the hobby, eventually spending too much time and money on it. If you've hit a brick wall with your interest, it may just be time to shift gears and find something new. Bear in mind, though, that shooting has many dimensions, and you may only be burned out on part of them. If you're tired of buying guns, stop shopping for them. If you hate the reloading bench, sell your press and components. If you hate the drudgery of going to weekend competitions, only do recreational plinking for a while. Believe me--I know. I've been into guns a long time, but I've regularly moved between its various forms. I've been passionate about concealed carry, milsurps, benchrest guns, rimfires, reloading, and tactical rifles, all in turn. If you do too much of anything, you'll grow tired eventually. For me, I'm tired of buying, selling, and trading. I've done a lot of that, and just yesterday I went into a large gun shop and actually felt disgusted to look at all the offerings there. NOTHING interested me. That doesn't mean I'm going to sell off what I have; I just won't be shopping for a long time. So, to come full circle, maybe it's simple burnout. Take a break. Try some new interests (gun-related or not) and see what turns your crank anew. Just have fun. If guns don't do it, no big deal. But hopefull something will. Good luck with it.
