I really struggle with my daughter

I have 2 children my 2 year old son and my 1 year old daughter. Me and my son have always had a really strong and close bond and I really love and enjoy spending time with him. However when I was pregnant with my daughter I got perinatal depression and was completely detached from the pregnancy and then after I had her I had severe post partum depression where I would say things like I don't want her this isn't my baby she hates me etc. I used service which have helped me bond and get closer to her but it feels like we just don't have the bond that me and my son do I find it really hard to stay calm with her and feel like she doesn't like me very much I don't know what I can do to help fix our relationship.
