No it's not nice. I know better than to say that to her. So if anyone can translate that into something I can actually say to a coworker that'd be awesome.

"( whatever her name is) this is a team and we don't think your pulling your fair weight in this team. All the little breaks and stuff isn't fair to me or anyone else here. We all have to push through and deal with stuff outside of work but we do it cause it's our job. If there's a problem you have that you can't work through let us know so we can help, if not, your gonna be judge on the lack of effort we feel your putting forth..." I've had issues with co-workers and didn't handle it the best way, hopefully this helps you.

That's extremely mean, unnecessary and uncalled for.
Yes you may have had permission to have words with her. But to tell someone they're a 'ugly fat piece of shit' 'no one likes you' and 'go die' I'm pretty sure is bullying. So far your rant isn't even work related as it's personal insults
