Ariana Grande is reportedly an emotional mess right now and has been drinking a lot lately as a way of dealing with her personal problems. Last week, the popular singer made headlines after breaking down onstage while on a show in Pittsburgh, Pennsylvania.

On Wednesday night, Grande cried in front of the crowd as she started to sing a verse from her song “Thank U, Next,” mentioning her ex Mac Miller. It can be recalled that Miller died of a drug overdose in his home in September 2018 while Grande was still engaged to comedian Pete Davidson. Shortly after Miller’s death, Grande called off their engagement.

According to reports, the singer’s recent breakdown has left her loved ones worrying that she may be going too fast in her career after all that she has gone through in the last two years. “She’s an emotional mess right now,” a source revealed. “Of course her family is worried. She has so many things on her plate and she has been trying to juggle everything while trying to also have some semblance of her personal life,” the source added.

The source also revealed that Grande is now more unpredictable than ever because of the trauma she has experienced in the last couple of tumultuous years. “Ariana has been so hot and cold lately and no one knows which version of her they are going to get and right now she is more unpredictable than ever,” the source said.

Grande’s trauma reportedly started when her fans were killed on May 22, 2017, by a suicide bomber during her concert at the Manchester Arena in London, England. The bomb exploded as her fans were exiting her concert at the arena, killing at least 22 people. The incident left Grande extremely traumatized that she stopped touring until later that year, when she hosted a benefit concert for the victims and families of the Manchester attack.

Just a year after the tragedy, her ex-boyfriend Miller died. Both unfortunate events triggered Grande’s post-traumatic stress disorder, causing the singer to depend on alcohol to relieve her stress.

“She is still drinking a lot and that has just made everything so much worse,” the source revealed. “Everyone is just praying for the best outcome right now, but she really needs to slow down,” the source continued.
