To try going viral is tragic (5-7)

I believe the answer is:

heart-rending

I'm a little stuck... Click here to teach me more about this clue!

'is tragic' is the definition.
(I've seen this before)

'to try going' is the wordplay.
'to try' becomes 'hear' (as in to try someone in court or hear their case).
'going' becomes 'trending' (I am not sure about this - if you are sure you should believe this answer much more).
'hear'+'trending'='HEART-RENDING'

'viral' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for heart-rending that I've seen before include "Poignant" , "Causing great sadness or distress" , "Agonisingly sad" , "moving" , "Greatly distressing" .)
