Prozac helped me after I had my youngest.
I think occassionally people catch mental "colds" and for some a brief period on meds may help while others it might experate problems.
I have a relative who has anxiety issues and they take ativan but only once in a while, like a few times a year. The same relative was put on anti depresents, which wasn't helpful to her problems, then put on anti pyscotics and that made her problems worse.
The problem is doctors play around to much with medications. They put someone on something and then it causes a side effect so they put them on something for the side effect. Drug A is causing patient to have insomnia so they put them on sleeping pills.
