Burnout is an emotional, mental and physical exhaustion. It can lead to depression so I would treat it as your body telling you something is wrong. Maybe start with a two-three possibly four week vacation totally unplugged and see if that helps you. However, you need to take a step back and look at the forest rather than the trees with respect to the demands being made of you (and that you say 'yes' to). These can be family demands, work demands etc... They build and build causing stress eventually leading to burnout and possibly depression. Also a question to ask yourself is "are these demands asked of me aligned with my values?". Many times we are living the lives of other people and not our own. So you experience an emotional dissonance. You also have to let go of the things you cannot control. You can't control the economy, you can't even control your job or necessarily the fate of your startup itself. If you stay, your company could implode. Since you have two incomes and can make some sacrifices maybe things will be ok. Also while you are on sabbatical or vacation or just in general you probably need to learn some stress management skills. I would take up mindfulness meditation and see what that brings you. Connect with the present. Explore your mind body connection. The people really into meditation say it works so may as well give it a serious try. Clearly something has to change and that could be something a simple as your perspective. Also I'm not really writing to you here, but rather as a note to myself.
