It happens i was depressed after i had my daughter for a whole year i was happy with her an blessed but sad with my life.. i even left my bf thinking it was him stressing me out but it was just me going theu depression.. alot of girls get it and don't know why and it's an ugly feeling but just know it's normal don't let noone tell you different. Im no longer depressed but so happy but i have my moments lol i just hope i dont have to go thru it again with this pregnancy.-
It may be your hormones, take it easy it's hard work having a little human inside you
