Post partum anxiety

I’m a first time mom and my baby girl was born 10 days ago. I wanted her so bad, so I’ve been really struggling with my feelings lately and this intense feelings of anxiety around my husband going back to work and having to parent on my own. My family all live in another country and can’t fly here right now due to boarder closures and I only have a couple of close friends here. My husband has been my ROCK. I can’t imagine him even leaving me for more than a hour which is also hard. Anyone going through similar or have before and can shed some light as to when it does in fact feel / get better? My baby breastfeeds mostly ok but doesn’t sleep on her own/ in a bassinet.
