@foreverreverof I am so sorry for all the unsympathetic and shit responses you have had on here OP.
Have you any other friends or family near you OP, because you sound very lonely to me? You have been following her on social media as she gets on with her life, and her being very busy with other friends, whilst apparently not giving you a second thought. I think that that probably hurts mentally even more than your poor broken wrist did physically, and having had a broken bone myself many years ago I know that the pain is excruciating.
I hope your wrist mended well and that it wasn't your dominant hand - although it often is, because if we put our hand out to try and stop ourselves from landing flat on our face, we usually aitomatically use the hand that we use the most!
I hope you had a partner or mum who could help you while your wrist healed?
Do you work outside of your home OP, if you do, are the people at your workplace nice, and were they kind about your broken wrist? We all need some sympathy when we are in pain, so if the friend you had to cancel on was your only friend then it is very natural that you felt let down by her and her apparent lack of care.
Maybe unfortunately, but apart from family (I am including romantic partners as family here), and sometimes not even then, no adult owes any other adult anything at all if they don't want to. But if one adult cannot put themselves out for another adult - especially one they are supposed to be good friends with - then that is (imo) very sad.
How long had you known your ex friend for OP? She sounds like she has lots of friends/colleagues/acquaintances, so she probably (maybe even subconsciously) does not need - for want of a much better word - you in her life, for her to feel happy and fulfilled (I am so sorry to sound so harsh, but I am trying, very badly, to explain why your ex friend probably wasn't behaving any worse than many other people would have in similar circumstances).
She may have such a wide social group of "friends" who she spends time with, that she doesn't actually feel very close to anyone in particular, which would go some way at least in explaining to me, her behaviour towards you. I do find it sad though that she did not seem to view your friendship with her in anyway near the same way that you did.
I don't know if my thoughts here can help you feel even a little bit better @ forever, but they are my true thoughts. I think that you must be a lovely, loyal and thoughtful friend to have, and I think that your ex friend may (maybe soon, maybe in many years to come) one day come to regret not cherishing the friendship she had with you.
I hope that what I am about to say doesn't sound condescending, or like I am preaching to you, as I can't claim that my own contemplations are right for everyone (or even for me!), it is just what my quiet and pondering times have helped me to consider, and it feels right to me.
As we get older our priorities can change, some in very small ways, and some in enormous ways, and that can be the catalyst for us to reflect on all sorts of things, including our present and past relationships. This may be one of your catalystic (I don't think that is a real word, but I don't care - why am I suddenly thinking of going bear hunting?) moments. A time perhaps to ask yourself whether it is important to you, or how important it is to you, that all of your relationships - whether they be close friendships, or romantic partners, or with a parent - are with people who share all the same ideals that you do? In my own experience it can be a very difficult road to try and find another me, and thank goodness I have realised that I would hate to do so, they would be far to exhausting and boring!
If you have got this far then you have my gratitude for doing so! I just hope that at least something I have said has helped, even if only a tiny way. 💐
