PPD or baby blues?

Having trouble telling the difference between the two. Definitely feeling down most days, not much happiness🤕. Looking at my daughter doesn't bring me much joy yet, thinking of the future doesn't help much either. I guess because I've never experienced it "getting better" or the milestones ahead. I worry about her being a fussy child, I worry about never getting sleep and having to go back to work, I worry I will resent having her. I miss parts of my old life. Only 2 weeks pp, will this get better or should I begin seeking help? 😔
