It's stated that Selena suffered an "emotional breakdown" following two hospitalizations within the last few weeks related to her Lupus and last year's kidney transplant.
According to TMZ, Gomez received medical attention at Cedars-Sinai in Los Angeles after her white blood cell count became increasingly low.
A reduction in the number of white blood cells is called leukopenia, and is sometimes common for those with active Lupus.
Earlier this year, Gomez completed a two-week treatment program in New York City for anxiety and depression. She is currently reportedly receiving treatment, including dialectical behavior therapy, at the same psychiatric facility.
"Every time I try to do something right, every time I try to do something good I felt like people were picking me apart."
"There won't be a day when I'm like, 'Here I am in a pretty dress—I won!' I think it's a battle I'm gonna have to face for the rest of my life, and I'm OK with that because I know that I'm choosing myself over anything else."
This is not the first time the pop star has sought professional treatment for her emotional well-being.
