No, it's not stupid, it's an attempt to deal with something positively, so it's good. One thing I practise all the time though, is letting go. As soon as you notice the triggering thoughts - which activate the negative feelings - begin entering the mind, let them go, quickly[!] Focus on something else. Let them go as if they were a disease. They are a disease, my friend, especially if regulating your emotions is a real problem for you, like me. Things like mindfulness and meditation are useful tools for that purpose.
