I injured myself at sports 3 weeks ago, dislocated my knee worse than I ever have before and have done some serious internal damage - waiting on the specialist to tell me if I need surgery etc but...

For the last 3 weeks I've been using crutches to move around, and because of the injury I can't sit at a normal chair, so I'm pretty much going from bed to the couch with my leg up (yes, I'm still working thankfully) however my concern is that my wife has been having to look after me a fair bit the last few weeks which is the opposite of our normal dynamic and while the injury and immobility has been hard on me mentally, having my wife look after me has been mentally difficult too as I constantly feel guilty having her do things for me.

We've spoken about this and she assures me she doesn't mind but I've still got guilt in buckets because of this and I don't know what to do, because she gets sick of me saying "thank you I really appreciate this" etc
