Is it normal to avoid apologizing to your former best friend?

I used to have a friend myself..her name was Zaire and she got leukemia ..I went to the hospital every weekends and took care of her,told her jokes... so anwyay she never appreciated what I did for her..She kept complaining i was disturbing her or my jokes irritated her...so I said OK should I stop coming often then? She said Yes please, Now go! I need my rest! So I came only once or twice and she started complaining that I wasnt coming often and she hated me and I was such an ignorant bitch so 'Fak off' she said. I cried but she shot her middle finger at me so I went home. She died but I have no regrets... I had cried extremely hard on her death and a girl called Olivia had come to the funeral..she told me they had been'The best of friends' so from then I realized she had been cheating onme. Hope you burn in hell , bitch. So anyway ..I am not EMO or anything but anyways...Ur friend ..She gets frustrated of you...it's maybe coz she's too sick and the fact that she isnt feeling upto it does not make her feel OK...get her flowers and books and lovely cards....spend more time with her in parks... get to know eachother even MORE . Do you like disney? Does your firned like disney? Yeah if she does bring her some cool classics and watch ittogether..If she does not like disney get her some of her favourite movies or classics and watch it together..My friend was not worth it...but yours probably is...give it a go..hope my advice helps :)
