Demi Lovato is an example of an artist who has been very vocal about her depression, eating disorder, and bipolar disorder, revealing that she struggled with suicidal thoughts as early as age 7. She further points out that such thoughts have reoccurred periodically throughout her life. Her story illustrates that the issue of depression is not so straightforward, and as pointed out in a similar post about Lady Gaga, it can't just go away -- relapses can happen, and that's totally normal and expected. Simon A. Rego, PsyD, a cognitive behavioral therapist, explains that "at least half of the people who have had a major depressive episode are at risk for more episodes down the road." https://www.refinery29.com/en-us/2018/03/194213/demi-lovato-depression-recovery-suicide-mental-health
