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

Pretend you are your friend. Imagine you are the sick one, you are missing school and fun stuff with friends, you are taking medications, feeling unwell and scared, and unsure of your future. How would you want your friend to behave? It's easy to put her illness out of your mind and go on with your life as normal. But don't forget her. She has been pretty clear about her feelings, even if not to your face. I think you need to spend time with her, apologize, and let her know she is important to you. It's not too late. This hits home for me because I've been in her shoes and had a friend disappear. It was traumatic for me. At any time I would've let her back into my life. But she decided that it was too difficult for her (and this is selfish, I believe) to make the effort when I needed her most.

This isn't truly an IIN sort of question, but you seem like a good person with good intentions

Just know that there will be times when she will be upset with you and you will have done nothing to deserve it, but you have to keep loving her anyway. She's lucky that you care so much. If you stick with her, I'm sure she will show her appreciation of your kindness one day.

I was once in an almost identical position to your friend. And let me tell you she will welcome your consideration.
Why don't you ask her to go for a coffee with you?

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 :)

O yah also, it's totally not normal to not apologize to your best friend. You got to!!

Aiight dude! The only best way to do this. And i used to do it a lot, cuz me and my frends are douches. So just go to her door and say it in person. And then you don't have to say so and so told me... just be like i realize your mad at me and i looked back on all the things that i could possibly have done to you, and i realized a lot of issues i did back then... I'm sorry i haven't been a great friend lately. My lust towards partying had taken me over for a little bit, but i must stay myself and be with you. And then admit the shit that you fucked her over with... I'm sorry i urged you to go party with me when the doc said you couldn't. im sorry i wasnt there for you and went to party... blah blah. and then, i promise to not let my judgement be clouded again by my selfish ideas and will you please be my friend again. LOL... I AM AWESOME!! But yah, do something around there. and when your pleading for someone back.. "they are usually right and your so wrong" even if u really dont think that. well yah, peaceya and good luck hun!!!

She needs you now more than ever in this tumultuous time in her life. Be there for her.
