Yes, these were heavy things and all piling up, till I had enough. The story is more complex, there were even worse things like this, so I had enough. (My mom was diagnosed with cancer and she passed away after 1.5 years. My dear friend vanished from my life completely, then after my mom's passing, she came back, telling me what I should do with my life. That's when I dumped everything she's done on her and told her I don't want to see her again.)
If you can't trust your friends and rely on them during hard times, better not have them. This is a classic example of with friends like her, you don't need enemies.
Oh, thank you Adrian, it wasn't cancer after all and I'm fine now, but it was a wake up call, to show how short life can be.
