Selena Gomez has been in rehab facility in Nashville,Tennessee since September, for depression, anxiety and panic attack.

The Heart Wants What It Wants singer, last post on Instagram has been in August. In one of her posts, she said to all her fans that she has been suffering from "anxiety, panic attacks and depression."

Things started getting really bitter after her breakup with singer Justin Bieber, who was accused of cheating on her and around that time she was diagnosed with lupus disease. Selena opened about it after rumours of drug addiction and while the time she spent in The Meadows and cancelled the Australian leg of her tour.

"I was diagnosed with lupus, and I've been through chemotherapy. That's what my break was really about. I could've had a stroke," she said in 2015.

Speaking to Fabulous, Selena's grandfather Ricardo Gomez, 61, who raised Selena for four years of her life, was surrounded by her photographs in his home in Texas.

Selena's grandfather opened up about her first stint in rehab. He said, "She was under a lot of pressure from work and was worrying about Justin. The doctor told her she needed to take time out."

He further added, "She works long hours every day, and although she loves her work, it got too much. I always tell Selena, 'Be yourself and don't let things get over your head.' But it would be hard for anyone. She's only human."

Selena got another blow when her friend, The Voice US contestant Christian Grime, was shot dead. Her death got Selena to break down in tears during a concert the following night saying: "I don't really understand how this happened."

Her fans filled her timeline with messages to support her and Selena then spoke about the side affects of her illness.

She said that she has "discovered" that anxiety, panic attacks and depression can be side effects of lupus, that can have its own challenges.

As if all this wasn't enough, she also got into a war of words with former boyfriend Justin on Instagram.Selena Gomez criticized Justin's threat to quit social media when fans trolled him for uploading pictures with latest lover, Sofia Richie.

Selena said that he should stop posting pictures if he could not handle hate. Justin replied to this with, " It's funny to see people that used me for attention and still try to point the finger this way."

Selena also replied to this saying: "Funny how the ones that cheated multiple times are pointing the finger at the ones that were forgiving and supportive. No wonder the fans are mad."

On the former couple split, Selena's grandfather said that Selena "loves him." But she does not wish to get back with him after his recent behavior. 

He said, "We've known Justin since he started in the industry and he was such a bright young man, but we worry for him. His family think Selena is a good influence on him."

Ricardo said that Selena has worked from the age of 10 and because of her crazy schedule, she couldn't devote a lot much time to her family.

He further said, "When we talk on the phone we say: 'We don't see you in person but we see you in the news, in the newspaper, the TV... Are you OK?' She says: 'Yeah.'

In her statement Selena told her fans that wanted to focus on her health and happiness: "I have decided that the best way forward is to take time off... I need to face this head on to ensure I am doing everything possible to be my best."

Hopefully in this time off, Selena Gomez gets better.
