Postpartum depression?

I had my little one just 10 days ago. He was very much planned and I am from the bottom of my heart so happy to have been so blessed! But the last few days all I have been doing is crying! Any time I'm alone all I do is literally ball my eyes out. I think to myself what have we gotten ourselves into? That I miss my life before baby and I find myself trying desperately to hold onto how things were before the baby. I miss my husband. When I'm awake he is asleep and vice versa. I am lonely and I just miss my freedom. Even as I type all this I shock myself because I never thought I would feel this way. On the other end I am so happy to have become a mom and excited about this new chapter in life. What is happening to me? I also have a lot of anxiety of weather I was cut out for motherhood and I am so scared to mess up. Has anyone else felt this way? What can I do to feel better? I spoke to my SO he is super supportive and tells me it's my hormones and that it will get better. Does anyone who has been through this have any advice for me? Thanks in advance
