I don’t understand Jinx

Like I swear I'm an idiot but I do not understand why Jinx wanted to die. Like is it just me or the part where she was talking to silco about the cycle and then let her hair down and was about to kill her self was so confusing. How did she get to that point? Maybe I missed things since I was more invested in the viktor becoming Jeusus storyline. Also why did she fake kill herself in the end? Another thing is how did VI and Jinx even reconcile that fast . Like VI and Jinx were about to kill eachother but when she finds Vander, she just goes to her sister and it's fine for a time being. Sorry if I'm going on a tangent but I'm just confused as hell. 99% of this is me missing things, someone explain this to me like I'm an idiot
