Have anyone ever experience hollucinations after giving birth?

After I had my first baby i went tru prospordum depression and i lost a lot of weight. and I started to see people that were not there. I felt like I was seen everyone for who they where good and bad. It was a very scary expirience. I became obessed with God. i started to believe that God lived in my Husband. I thought I was the queen of man and i was devoted to God. I thought most woman wherebad and God was trying to tell me that men have gave women to much right. One time I was watching tv and I saw that everyone was ill and corrupted and no one cared for each other any more. I was hospitalized for 2 months. When i came out of the hospital My husband would walk with me out side to watch the sunset with him and the second day i was home we look at the sunset and the clouds opened and My husband and i saw a city in the in the sky. I asked him do you see that and he held me and he said yes lisbet i see it. a little while later the cloud turned into a shape of a # 1 just like that ( #1) and he told me you see what God is trying to tell me that u are my number one. I tell you what when i was going thru this mental state i never felt so much fear as well as peace in my heart. It was an experience that i will never forget. Its been 2 yrs since my mental brake down. And I feel like the devil is trying to brake me. Because I start to recently to search for porn and yes I watch about 2 or 3 movies.my husbands been working a lot and i began to feel alone and bored with myself. I felt like god left me because I havent felt that peace i felt when I got sick. Today i found out that my name means Devoted to God. Has anyone ever experience anything similar? and why do you think this happened to me?
