I sympathize with you!/ Empathy/Sympathizing

I am very sorry to those who have been deceived or betrayed by a significant other. [ I think anguish is a bit awkward here, like "that causes me anguish" would sound more natural.] Nothing can be more painful than that feeling. Nothing can heal the deep pain in their hearts, nor can time be useful to extinguish the fire inside [I'm not sure I understand this part correctly?] I am also sorry for those who are still suffering from the faults [or mishaps, errors, etc] of their parents, for those who discovered that their beloved parents were murderers, drug traffickers, or robbers. I deeply sympathize with all of them [You could replace sympathy with empathy if you personally have been in their situation. Overall great entry!]
