When I sit certain tree stands often times deer don't start coming in until 30 min before dark or even right at dark (what I like to call prime time). If you have a spot like this ( field edge, apple tree, ect. ) you could try getting in stand maybe an hour before that prime time to shorten the down time. Once you get used to it or start enjoying it again, you could gradually increase your time. Other than agreeing with some of the others suggestions thats all I can think of. Good luck and I hope you are able to find that peacefull fealing again.
