I'm not sure you are really understanding.
Most people experience episodes in their lives that are difficult - bereavement, illness of children or maybe aged parents, domestic crises etc. These can be managed by existing protocols - maybe emergency leave, carers leave, unpaid leave, sick leave if necessary. I've had to do this.
Reasonable adjustments cover conditions that will exist in the long term, even permanently. A blind person might need adjustments, maybe specialist software, another person might need a ramp installed or an adapted chair. These issues aren't going away in a few weeks. Without these adjustments many people simply would not be able to work.
You say your friend doesn't want to take sick leave and why should she? Then she could use her annual leave. I have to use all of my annual leave to cover my hospital appointments, but why should I?
but I never saw her as a disabled person which she liked I treated her like the others in the team.
That is how I want to be treated. I hate drawing attention to what I can't do. I only want people to see what I can do. BUT if my manager decided to do some team building exercise that involved climbing up a mountain where does that leave me? Should they expect me to walk up it so that they are treating me like everyone else in the team or actually does that exclude me?
I don't want to have the metaphorical pat on the head but I am not able to do the same as everyone else.
Most people I know go to work, take care of their homes and family, have hobbies, socialise, go shopping. My life doesn't look like that. I go to work - that is my priority. Then I do my physio to try and keep me well enough to go to work. I do one housework task a day. If I want to socialise I have to plan it for when I have a few days off work because it causes so much pain and tiredness that I can't function at work.
This is the background that I have to work from. My starting point isn't as a fit and able bodied person who then has to worry about family problems. Anything over and above my illness is virtually impossible for me to deal with.
This isn't a sob story. I am incredibly fortunate when compared with others. Your friend is in a very very difficult place right now but it will improve. Until it does, there are mechanisms in place.
A month or so ago I suffered a sudden bereavement in the family. I received a phone call at work and had to ask to be allowed to leave - literally to arrange undertakers to the house etc. I had to ask for this extra favour on top of already booking leave at short notice and shift swapping for hospital appointments.
Long term illness or disability adds another layer of difficulty to life. Reasonable adjustments are meant to try and level the playing field a bit. They aren't perks.
