someone please comment 😓

Im 5 months PP. I'm experiencing a lot of anxiety that I don't usually. I snap at my husband. I'm just feeling overwhelmed and stressed out for no reason. This is number two and I never felt this way last time. My kids are perfect. They sleep well and nap well. I eat good foods and exercise but still this anxiety seems overwhelming. What can I do? I'm scared to see my doctor because she will think I'm insan e.
