Depression on Day 18

I'm looking for advice from those who may know something about Depression during a fast. I'm on Day 18 and for the past few days I'm continually in tears. I don't want to get out of bed in the morning. I struggle just to get through the day at work. And I broke up with my boyfriend on top of it all. I have never experienced anything like this before while fasting and it's scaring the heck outta me. I don't know where these feelings are coming from and have no clue what to do about them. Has anyone experienced this before? I'd hate to break the fast if I'm breaking through something deep rooted. But at the same time, I've never been this miserable before in my life. Suggestions anyone?

Much thanks!
