It can be so frustrating at times and it's only natural to suddenly snap when the annoying things are going on 24/7. I try to leave the room, if he says something that really upsets me I will just walk away to another room for about 10 mins. Hubby is in hospital at moment after lots falls in one day, I visit him everyday and hes really grumpy, downright nasty, says horribly things to me, so I will walk off the ward, for 15 mins , go to cafe and have coffee, scream to myself in my head, then calmly walk back to see him on ward, hes normally calmed by then for about 10 mins anyway.I know exactly what you mean, we just can’t accept that they’re not still in there somewhere! xx
