Going to echo what others have said, if you can actually afford to support yourself for that long then I would just leave and do something you want to. Go travelling for sure bud! How many people wish they were in the position to be able to do it and never did, don't be one of them. You wouldn't even spend a years worth of what you have saved up and could have something no job will ever give you. Go away, come back probably with a different perspective and then find more work. The gap MAY look bad, but you can just say you worked your ass off for x years in order to do something you always wanted to, see the world. I can't see any employer holding that against you, would be different if you quit and did nothing in that time.
