How soon is too soon to take meds for baby blues?

Since the 10th (one day after my baby was born), I have had some pretty serious mood swings. My doctor told me to call if they didn't get any better, so I called last night. My doctor wound up calling in a prescription for me for some meds to help. Am I being silly to go ahead and take this medication to get back to feeling like myself sooner, or am I being silly to not work through this on my own? I know it gets better, but it has been awful. I guess my main question is how early is too early for medication? Any help or guidance would be awesome! Thanks in advance!
