Speak to your boss if needed
If you feel you need some help with your workaholic ways by all means please speak to your boss. Does this mean you should admit that your life is out of order and you can’t handle things? No but there’s nothing wrong with discussing some alternatives to your current situation, especially if you come up with ideas that could enhance your productivity. Maybe there is a new schedule you can draft up or an extension you can get for your projects. You never know what solutions are out there until you open your mouth and ask.
