shellbell my baby blues lasted about 2 weeks. It was awful. I eventually went to my dr after a girlfriend noticed and was worried about me. After talking to my girlfriend and my dr I felt great, just being able to talk about how I feel and know that this is completely normal!! I also started to do 'normal things', like going out for lunch with someone, or going shopping. I found that was a great help.
They say the baby blues start from around day 3, so don't worry too much. If you can, leave bub with someone, even for an hour, and have some time for yourself. You'll feel great afterwards
