'at the end of her rope' with husband Kanye West

is reportedly feeling powerless once again amid husband Kanye West's continuing erratic behavior.

Amid a flurry of troubling tweets this week - some of which resulted in Twitter suspending his account for 24 hours - the 43-year-old rapper raised concerns even more on Friday as he posted a message about 'going to war' and his fears of being murdered.

Just two months after Kim and Kanye had marriage crisis talks in Wyoming it seems this time the 39-year-old Kardashian is going to struggle to keep her marriage together as sources revealed Friday she's 'at the end of her rope'.

'He's off his meds,' an insider told PEOPLE. 'He promised he'd stay on them. The last time, part of his negotiation with Kim was that he'd get back on his medication and he would work very hard to control his impulses. 

'He made a lot of promises. And now those promises are broken, less than a month later.' they added.

Kanye and Kim wed in 2014 and share four children together, daughters North, seven, and Chicago, two, and sons Saint, five, and Psalm, one. 

And Kim reportedly feels like 'she can only take so much' as her husband of six years appears to be going through another bipolar episode. 

'It's the same thing over and over and over again,' the source said. 'He's on very thin ice with her right now, and she's truly trying to decide what to do to protect the kids, but also her own sanity. The whole thing is discouraging and difficult for her.'

The E! star was apparently taken aback by Kanye's latest tweets and wants him to 'take care of his own health'. 

'She can't force feed him medication. She can't make him do anything he doesn't want to do.' the source added. 

Early Friday morning Kanye concerned fans as he shared - and then deleted - a troubling tweet in which he expressed paranoia about being murdered and having his eldest daughter taken away from him.

'NORTHY I AM GOING TO WAR AND PUTTING MY LIFE ON THE LINE AND IF I AM MURDERED DON'T EVER LET WHITE MEDIA TELL YOU I WASNT A GOOD MAN... WHEN PEOPLE THREATEN TO TAKE YOU OUT OF MY LIFE JUST KNOW I LOVE YOU.' he wrote.

Along with the message Kanye shared a photo of North looking playful and throwing up two peace signs.
