This is the only real answer here.

Every other answer is in some way just making your perception of time accelerate.

But the only way to process emotional loss, of a close loved one; is with time. That’s just the way our brains are wired. We couldn’t survive as a species if we didn’t get numb to pain and trauma in the past.

Time with no contact. Any contact with the person and you are reopening the wound. Unfollow, block, they don’t exist.

Yes, time. But what do you do while the memories fade and replaced with? Friends, family, work, hobbies. I picked up a guitar after a devastating break-up that ate a lot of that time needed.
