Hypoglycemia diabetes symptoms and conditions

I've taken Yaz for the past 18 months. It was fine the first few months, then I started to get severely depressed - suddenly and for no reason. I had a hard time wanting to live, despite the fact that I have the "perfect" life as a stay-at-home mom, 2 kids and a wonderful husband. I also would feel like crying quite often for no reason. Everything else was fine: regular periods, good skin, no weight gain.

I recently quit yaz, about 6-8 weeks ago because of the mood swings. This is how I feel nearly every day since: shaky, crazy in the head, headaches (which I never got before), full of anger and outbursts at my children & husband, jittery and sleepy in the afternoon (like I have low blood sugar or something). I really feel like I'm going crazy. I'm going to go see my doctor this week to see what's up. I was considering hypoglycemia, diabetes, or thyroid problems, so I'm glad I found this site and considered yaz as the culprit.
