Pp anxiety

So I just seen a post asking about mom's who had postpartum anxiety or depression. And I honestly just thought it was me. I'm having such bad anxiety about going out anywhere. Especially play groups I've been trying for a few weeks now since the weather's getting nicer but I always chicken out cause I'm scared but I can't think of why I'm scared or anxious about it. So it's not like I know how to overcome it. The play group are at different places and times daily but the same every week. How do you overcome this anxiety?
