Hi there,
Iv had a similar experience to yourself. Im 26 and four and a half months ago gave birth to my first baby. Within 8days i started to feel extremly high and happy, i had an enourmous sense of well being and wanted to do EVERYTHING, see EVERYTHING, Learn EVERYTHING. it was like i was seeing the world through new eyes, everything seemed fantastic and amazing. I went to the supermarket and was there for 3 hours looking at everything and ended up spending over £300- my usual shop would be £40. I also had many delusions, such as, i thought my partner was from outerspace sent to protect me, and at one point i thought my baby was jesus, i thought i was evolving and that was why i felt so great and that everyone else around me was feeling the same as me or would do soon. i thought i had the answers to all of the worlds problems and was convinced that i could acomplish anything i wanted to. Around 12 days after i had my baby my family and doctor managed to convince me to go to hospital (mother and baby unit), volintarily. When i got there i was convinced i was there to help the doctors, help them learn from me because i knew everything and had all the answers. They diagnosed me with puerperal psychosis, and said i had been suffering from a hyper manic attack and started treating me with antisycotics(rispiridone). Around two weeks later i started to come back down to reality and was able to come home. Unfortunatly after my incredible high, the drugs brought me right back down- to far down and i plunged into a deep depression, all through christmas. luckily it only lasted around 3weeks because the doctors managed to find me the right anti depressant to bring ne back up to the right level. Now im almost back to my old self. I was told that if i wanted to have more children that there was a 20-50 percent chance of pp returning. But they can treat you for it during the pregnancy and straight after the birth to help prevent it. As far as i know, if you did get it again , they would not take your baby away from you again, they would treat you in a mother and baby unit- thats what happened to me. I would speak to your doctor, he will be able to answer all of your questions alot more acuratly.
Good luck! x
