I want to start collecting Pusheen again but..

So back when Pusheen was still new I had gotten a medium pre Gund Pusheen plush from my ex boyfriend in 2012. I had loved that thing but when we broke up I was really sad and end up donating it around 2017 without a second thought cuz I was still upset. I had kept it in the closet for a long time. But seeing new Pusheen plush makes me want to start collecting again. But I'm still sad I donated my first Pusheen plush. How do I move on 😩
