Only three videos were left on Big Sean's Instagram account Monday. In them, the 31-year-old marked his birthday by sharing the details of his battles with depression and anxiety. As it turns out, he said it started around this same time last year. "I felt like something wasn't all the way connecting with my energy." As InsideEdition.com's Stephanie Officer explains, Big Sean may have revealed a clue at that time about what he was dealing with.
