I was put on fluoxetine 20mg a week after having my baby for severe blues/pnd. That was 6 weeks ago...I felt worse initially then better...had a few good weeks...then started to feel anxious and low again...came on my period and upped my fluoxetine dose to 40mg a day on friday. But today I feel so much worse. I woke up with anxiety...feel back at the beginning. Can increasing the dose over 2 days make you feel worse? Will it get better if I persist with higher dose. I'm so scared.
