I have a long standing pen friend in another European country - we exchange messages almost every week. This dates back to about 2010. We met once when she and her husband and her best female friend came to England in about 2017. For the first 10 years her life was really stable and generally uneventful and she has always been a buoyant positive personality: she's actually an American but she's lived there for over 30 years. Unfortunately, the last 5 years of her life have been very difficult as her husband has fallen ill - initially, for at least 2.5 to 3 years, they were unable to give a diagnosis - they thought it might be early onset dementia, then a first psychotic episode, then schizophrenia and then they tentatively diagnosed catatonia - which he had shown clear signs of right from the beginning - but the thought was that that was part of something else but different types of brain imaging failed to identify conclusively what was going on. His illness had caused her, (their!) lives to collapse: he was unable to work so she has to give up her job to care for him and they lived off her careers allowance and caring for him has been difficult. She had to sell the house they were living in and rent somewhere. He has now just had another severe downturn in his health and has had to be admitted to hospital until they can find him a care home where he will live permanently. As a consequence, she is losing her carers allowance and has, in the space of a week or so, had to find somewhere else to live, to rent - she'll live alone in a tiny one room flat. I have always kept in touch with her throughout all of her troubles as I am not a fair-weather friend, but her latest problems do stress me and right now I feel quite worn down by all of her problems - but God knows how she is continuing to manage to keep moving forward but she's now facing another massive downsizing in her life. I know she appreciates that I always keep in touch. I know she isn't a person whose life has always been full of problems - you can sometimes think that people with a lot of problems are partly or entirely to blame for their situation but I know, in her case, the problems all stem from events totally outside her control - she has just had so much bad luck. Right now, I have run out of positive things to say to her: she must be devastated at the way her life has been changing over the last 5 years, I don't know how or even if, I would have coped, so I admire her in many ways but I can't see the point in saying so many things - no point in telling her how terrible this has been or how much I marvel at how she has got through it all - she knows all that. My life is fine, I don't have much to moan about but I'm always mindful of not talking about things in my life that might cause her to compare her life to mine but over the past 5 years I feel like I'm running out of things to say, or ask or talk about. I like this person, respect them, have enjoyed our friendship and don't resent her for the situation she's in but it's painful not being able to do much to help her and watch things go from bad to worse.
How can I continue to support her given the latest turn of events in her life and how I am currently feeling?
