Kanye West didn’t handle the "pressure" of fame very well.
The ‘Only One’ hitmaker was hospitalised in November after suffering from sleep deprivation and exhaustion but things had started going downhill for the rapper in late October.
A source said: "The pressure had gotten to him and he didn’t handle it well. He made himself exhausted. But [the exhaustion] was a symptom of the problem, not the problem itself … He wasn’t making a lot of sense when he talked, and he was texting a lot of strange stuff to people. Not dangerous, but he just didn’t make a lot of sense.
"Part of loving Kanye is that he sometimes is talking on a different level from you, and you just listen. But this was a lot more alarming. When Kanye gets like this, he doesn’t sleep. So you’d wake up to like 20 texts. The more tired he got from not sleeping, the less sense he was making. He wasn’t in a good head space."
And whilst Kanye and his wife Kim Kardashian West are reportedly going through a tough patch at the moment, an insider believes it will make the couple’s relationship stronger.
They told People magazine: "Kanye loves Kim very much, and he adores the kids. He would take a bullet for them. They’re his whole world.
"If [the family] can get through this, they’ll be so much stronger. I want them to be happy, and I think they will be happier together than they would be apart."
Meanwhile, Kim is reportedly "annoyed" at her husband for not following doctor’s orders and resting.
A source said: "Kim still denies they are getting a divorce, but things are definitely not great between her and Kanye. Kanye is supposed to rest and focus on his mental health.
"Instead, he has had a very busy week and is done resting. Kim acts annoyed. She also seems miserable and is spending a lot of time with her family."
