Honestly, I don't think more of the same is going to help you feel less burned out. Obviously your couple of sentences doesn't give me a lot of insight into your life, but you do not seem to enjoy your job, and that is going to color your whole perception on anything related to it. I think I'd honestly recommend you start looking for work you actually enjoy, but if that isn't possible I recommend unplugging as much as possible for awhile. That's the only way I've ever had the spark come back for me. Starting side projects always lose their luster after a session or two and just started to feel like another source of stress for me.
