Stressed..

Today has been a day.. my 4 year old hasn't listened, he won't eat anything but junk, won't behave.. I'm pregnant and extremely fatigued as well as my emotions all over the place.. I've yelled, cried and apologized so many times today and I just feel like the worst mother out there.. I have ptsd and haven't been able to take any of my meds since I found out I was pregnant and I cannot wait to get on something that works while being pregnant.. I really feel alone in this but I'm sure I'm not..
