TRIGGER***Worried about postpartum depression

Before getting pregnant, I was a very anxious person. I don’t think I was any more depressed than the average person but for some reason, the thought of postpartum depression scares the crap out of me. I do feel I may have minor antenatal depression so does that mean I’m at higher risk for PPD? I’m 11 weeks and find myself just crying some days. Ill worry about finances or labor etc and just get myself into a funk. I hear all these stories about women committing suicide after the baby is born and it scares the shit out of me!! Has anyone experienced postpartum depression? What did you do? I can’t help but worry about every little thing now 😢
