It sounds to me like you're burnt out. I think it might be helpful (if possible) to take a break completely for yourself, in a new environment - even if it's 3-7 days. No work, no family, just a place for you to relax and think. If coding isn't something that you feel ready to do anymore, perhaps you can move into a more management/biz oriented role?

As for the increasing difficulty of webdev - it's worth considering how necessary some tools are to the project. Oftentimes things can be simplified. It would take research, but maybe if you wrote a well thought-out and documented assessment of how you can simplify, your company might consider it? Good luck
