I lost someone young in my family to Covid last year. The chilling words "We have lost him" came on Whatsapp as the entire country was in lockdown and we were in a different city. I cannot forget it and keep going over it, over and over again.
I am sharing this to let you know that this happens to a lot of us. This grief will not go away. I just relive it everyday for some time. I am also a workaholic so it helps that I dont have much time to think. Yes, lots of people talk about therapy, meditation and a lot of things but I have never found anyone who is suffering to have gotten help from these.
Just live with it, what cannot be cured must be endured.
