Cortisol....

So, I've heard that stress can cause our bodies to produce too much cortisol which typically causes belly fat to develop. Okay, so I've been really stressed for about a month now. I have tried everything--working out, prayer, meditation, etc. It seems like I can't get it together. I feel tense about 90 percent of the day. Sleep is elusive and I rarely get more than five and a half hours a day. This is causing my weight loss to plateau. I'm starting to get frustrated...what am I going to do???? Ugh!!!!!
