medication depression/anxiety?

Hi. I need help. Ive always been an extremely anxious person. Well now since the baby (4mo ago) it's been x 100....It's ruining my every day life and the people in it. I've taken Xanax in the past but I don't think that's what I need. I'm constantly thinking my baby doesn't know who I am. Constantly thinking people are bad talking me. Always worried I'm doing wrong. My mental state is not good. I don't know what to do. Anyone have similar issues? I never see my PCP but thinking of going and asking for help. I need something. I can't just flip a switch. I've been this way since I can remember. It's just gotten so much worse! I feel miserable. Any tips? 😞😓
