Two weeks PP

I just look in the mirror and want to cry. I'm losing about two pounds a day because I'm not eating because I don't have an appetite at all. Getting really no sleep. When I can actually lay down to sleep my mind just races nonstop about everything and next thing you know he's up again and I missed my chance to sleep. My partner is absolutely amazing doing everything just right and yet I'm still just sad. I need help ... just to embarrass to ask for it. Idk why I'm so weak ... ik I should be stronger
