12 weeks left!!!😅😥😖😆

Only 12 weeks till my bundle of joy gets here and I fell completely tearafied and excised. I'm a FTM, 21yo and married. I've worked with kids for 7+ years but having my own is opening up a whole new can of warms. Is there any advice anyone can give me for FTM, young mom, breastfeeding, how to hadle PPD (I already have MDD & anxiety so dr said I'm at a higher risk for it), or really anything in general? It would be greatly appreciated!!!! And thank you, in advance!!!
