Fell out of love with my collection

I thought it'd never happen but after 4 years and thousands of dollars I have fallen out of love with my collection. They're all just in boxes but the idea of selling makes me so sad because this hobby was my absolute love and life. It may be due to growing up or the lack of new games recently, I'm not sure. Just holding out hope that the next pokemon game will change my mind and bring me back into it :(
