Advice please😔😔

I just had a my baby boy a month ago.. my anxiety has been so bad it's hard to deal with it everyday someday it gets so bad I just want to cry. Someday I'm mad at my fiance for no reason like I hate him but I have no idea why. I love him so much. But lately all I do is pick fights with him. IV always been a germaphobe and that has got so much worse since iv had him. I don't even want no one to come over and see him. When my sister and nephew want to come over I get so pissed off and my anxiety goes threw the rough. I didn't even want my friend to come over and see him. And when they come over I feel like I make it uncomfortable for them because I'm so worried and so sad. Anyone else go threw this? Should I talk to my doctor? If so what kind of medication did they out you on? Did it help? I got my tooth (12 year old molar) pulled on monday and they out me in this medication for the pain and it makes me kind of loopy and tired and honestly it's the happiest iv been. I just can't take feeling like this anymore. Some days I feel fine so I think maybe I don't need to talk to anyone but I feel like I have more bad days than good.
