is it possible to have false memories about things that are not stressful at all just remember something and wonder if it happened or not

You think they're false memories, but you're not 100% sure and you're obsessing about determining with absolute certainty they're false. If that's the case, ERP may be the best option for you. It's not easy first, but you need to accept some uncertainty, let it grow on you, and you'll notice after a while that those intrusive thoughts won't bother you anymore.
