Firstly, you seem to be over-stressed. Also, you have symptoms of lack of sleep and nutritional deficiencies. I suggest that you take advice from your obstetrician and have a consultation with a nutritionist and also a psychologist
, if needed. As of now, I feel that is the only way out. As far as your diet is concerned, you should take plenty of fruits, excluding papaya, plenty of whole grains, lot of water and dairy products. Take as much rest as possible and try not to over-stress yourself. Wish you good luck.
