Lemon I hope you feel better very soon.
PILs have already palmed furniture off on us. About 15 years ago they gave us a very long sideboard they'd had since the 60's. I told OH we didn't have space because we already had a sideboard and he did the "oh, let them give it to us" thing. It went in his garden shed because there was not space inside the house. He doesn't have a shed now and I don't know how he disposed of it. We currently have their old rug which OH has had to put in the study because there's nowhere else to put it.
I do struggle still at times, but I'm much better at letting go than I was. My problem stems from insecurity, which I've dealt with but little pockets of memory open up and I find myself thinking that I might need this or that when I know in reality that I really don't. I had a set of 6 mugs, a gift from my mother that was was supposed to be for display because "they're hand painted, you can't wash them up" they broke along with everything else when the kitchen cupboards came off the wall - don't ask- and I've managed the last 5 years without them.
I've realised I can't take the recycling today as I'm waiting in today, but it's in the car ready to go.
One thing I'm dreading about the potential move back to UK, if we can sell here, is ILs being able to buy us gifts again. It's awkward where we live so the sets of two glasses, brandy & Irish coffee etc, and little nick nacs have stopped arriving and we've recycled what we had and I don't want the yearly supply to start up again. Even before I realised I needed to declutter my sister bought me lovely miniature glass things, twice, and when she said there are 17 in the set I actually froze.
I probably sound like the DIL from hell, but I can't see why I should live in someone else's clutter and make myself ill by doing so. Plus my parents are both deceased so there's no more crapula filtering down from my side
