Waking routinely 2-3 times / night could be doing it! That's some serious sleep deprivation. Prisoners don't even get that treatment. 7 months of that is really harsh on your body, too. Getting a few sessions/week of 30 minutes of break-a-sweat kind of exercise (ie jogging, running, biking, swimming laps) will regulate hormones and reduce stress too. PPA is post partum anxiety. I suggested it as a potential thing to look into because of the number of times in your post you mentions the word stress or similar words (stressors, upset, frustrated).
