You may feel you can't deal with sorting out your partner's things at this time, but at the same time, you can't bear to see it every day.
Maybe you feel overcome with grief everytime you come across an item of clothing that your partner used to wear, or walking past their home office where they used to work from, or seeing their coffee cup everytime you open the cupboard and you feel you have to get rid of it in order to survive.
If you have a close friend or relative, ask them to help you pack away everything and put it in storage. Maybe you want to give away some items immediately, but my advice would be to wait for a couple of years. You and your family may not realise at the time that you should have kept certain items after all, and once they're gone, you can't get them back.
If you put the items in boxes in a spare room, at least you won't have to see the items every day but you know that there are there should you want to.
If you can afford to, keep paying for subscriptions such as Strava, Apple Music, cloud storage, email accounts etc. until you are ready to deal with it.
