Hi netti,
Yes, Andrea's right, I find having someone around that is an understanding nonOCDer helps in these situations. You don't need them for reassurance, but a little encouragement goes a long way
Even without OCD it's easier to do this sort of things with someone else.
My OCD is really bad and when my mother died last year I must admit it was hell packing up her place. But that was as I'd just had a breakdown and not only did I have a limited time to do it the family kept interfering and confusing me. On the days that I had someone helping constructively I was able to do it.
Use it as an opportunity to go through everything in the house and throw it or take it to a charity shop if you really don't need it. Give yourself plenty of time to pack etc. I had to do it in a hurry and as a result didn't know where anything was and brought back to my flat loads of things that should have been thrown. So plan ahead and label all the boxes, everyone kept taking my labels off
Although I hate it back in my flat if I hadn't come back to it I probably wouldn't have met you all as my mother wouldn't allow me to have the internet. I'd love a fresh start in a new place, I wouldn't then have all the bad memories that help to trigger the OCD
Just think of all the fun you can have creating a new little sanctuary.
Planning and pacing yourself is the key to not getting too stressed with a move and try and get someone to help. It's so much easier as you don't get distracted and it's also much easier to make the decision to throw something away rather than keep it for keeping it's sake.
We're all here to support you.
All the best
