Postpartum Anxiety

I’m 9 weeks postpartum and I’ve never had anxiety in my life and ever since I’ve had my little one it has been so bad. I feel like I can’t breathe and my mind won’t stop racing. I have been very depressed too. I’ve been on a antidepressant now almost 2 weeks and have been eating healthy and exercising daily but nothing seems to be helping. If you’ve experienced this what helped you?
