Can't go to the scene to mourn?

I can't go to the scene to mourn. It can be said:

I'm very sorry to hear this bad news. What I want to say is that although I can't be there in person, I will always accompany you. Or to put it this way, all the sadness and pain will pass, and I wish you all the best here to tide over this difficulty with the support of mutual care and support.

if you can't attend the mourning activities in person, you can express your mourning feelings by writing letters, making phone calls, texting or through social media. These methods can convey the meaning of care and support, and make family and friends feel comforted and concerned.
