I'm looking for a bit of advice.
For context -
My father in law was diagnosed with cancer about 1.5 months ago. He has three children including my husband. My husband and I live the closest, about 30 mins away. My FIL has been unable to drive since the diagnosis due to taking strong pain meds and my MIL doesn't drive. They live about a 15 minute drive away from any supermarkets. My husband and I are expecting our first child, I'm currently 24 weeks.
FIL has been having regular appointments to do with his PICC line etc although hasn't been started on chemo yet due to complications of surgery and a couple of other things.
The thing I'm struggling with, is the fact FIL and MIL just expect him to drop everything and move shifts around to take them to appointments without any consideration on how it's impacting him. He's a paramedic and had to take FIL to an appointment in between two 12 hour night shifts the other day, then go to work for another night shift. He ended up having to come home at midnight due to a severe migraine and was violently sick.
I can tell he's struggling to cope but he won't tell them that. The other siblings don't seem too keen on helping transport to appointments. FIL & MIL forget that travel time for a simple 20 min appt in total equates to at least 3-4 hours out of my husbands day off or before/after work time, then they expect him to take them to the supermarket afterwards for shopping each time. This is happening at least twice a week, alongside calls daily to ask him to go over, bring soup, collect medications etc etc.
I've suggested online food shopping which they don't like the idea of because they can't have same day delivery. I've suggested PTS transport occasionally to hospital appts which has been ignored. I said I'd take FIL last week to an appt on my day off, 30 min drive over to theirs only for them to say they'd felt unwell all day and didn't feel up to it which I was really quite annoyed about because the lack of consideration - I'd only spoken to them 2 hours before to confirm.
I know FIL and MIL are trying to deal with a cancer diagnosis, I know this and absolutely sympathise. But I don't feel like they recognise or perhaps even care about the mental and physical health impacts this is having on my husband, their son. I'm speaking about it to my husband and he simply looks so drained by it all. I feel I'm going to have to say something to one of both of his parents because it can't continue like this for however many months or years this goes on for.
Does anyone have any suggestions how I can sympathetically but firmly address my concerns? Thank you
