I lost my Whatsapp history of ten years

Due to technical issues. There is no getting back. Over 2000 images, hundreds of Videos and voicemails.

But the most hurtful part are all the memories of my deceased wife. Our whatsapp chat was such a big photo album. All the lovely voicemails hearing her sweet voice saying to look out for me and that she misses me.

I suffer from depression and am going through a horrible Phase. Why does life keep making it harder.

And why does every aspect of mindfulness go overboard in situations like these.

I would appreciate your advice.
