Hi, Greta, Welcome! So good to have you here.
Perhaps you could start by selecting 10 things that you’re attached to that no longer serve you and you need to let go. Then have a private good bye party or ceremony to bid them adieu.Then get them out of your house, maybe to your car so they are ready to take to where you will donate them. If nothing else, the saying of thank you for your years of service and now goodbye could be what you need. You could make a separate pile of more valuable stuff and hire someone to sell them on Ebay for you if you didn’t want to make a plan to put them up yourself.
