No, for the following reasons:
1) Truth is an absolute defense to a defamation case; and a good-faith belief that a statement was true can be as well. If the CPS worker had reason to believe that their statements might be true, then they would not be liable for defamation.
2) No lawsuit can win unless you can show the nature and extent of your damages, in a legally cognizable way. "Emotional abuse" does not count. You must show that you suffered a specific harm, directly caused by the defendant's actions and not by any intervening factors. (Some kinds of false statements can be considered 'defamation per se,' and can be inferred to have caused harm without a specific showing; but you still have to show the extent of damages in a way a court can redress.)
3) Government agents are generally immune from lawsuits for actions undertaken in good faith in the course of their duties. Oregon's Tort Claims Act does allow for an exception, if you give notice to the agency or municipality you wish to sue within 180 days of the incident - after that, if you haven't given notice, you're permanently barred from suit - but there is still a sovereign immunity claim to be asserted.
4) If your goal is to have people stop saying bad things about you, then suing them is likely counterproductive. People have this notion that suing someone will be this glorious redemptive process, where their every injury will be avenged and all their feelings validated. This belief is staggeringly wrong. Lawsuits are intensely unpleasant. They force the parties to live through whatever injuries they originally suffered, for months or years. You have to answer tons of difficult questions, over and over again, and if you change your story even a bit, you can be sunk. They rarely go perfectly - the law often produces results that one side or another considers to be unjust, for technical reasons - or just because "justice" is a pretty subjective concept. The other side has every motive, and every right, to attack your honesty, your conduct, and your motives. And, of course, you need to shell out a fairly large amount of money, most of the time. This is true even if your lawyer is working for a contingent fee, where they don't get paid if they win. And it's certainly true if you lose, and you have to pay the other side's attorney fees, which can be huge. In defamation cases in particular, because truth is a defense, the other side has the incentive to argue that the statement really was true - and even if it wasn't, it'll be repeated thousands to times.
If CPS shows up again, consult with an attorney at once. Otherwise, do your best to move on.
