I suspect you already know the answer to your question. Yes, gossip can destroy your life, but only if you allow it to do so. We often hold on to incidents long after we should have let go.
Do you lie awake at night about what happened to you months ago? If you do, do you think those people lie awake about you? I can assure you they have probably forgotten about you already, and they will only remember if you keep reminding them.
It is time for you to let go of these people.
You have learnt from them that it is not nice to be bullied, and that it is important for you not to bully people. You have also learnt that gossip hurts people. Therefore you should not gossip about people.
You have also learnt that even if you did not mean it, it is not right to threaten a person, whether it is a man or a woman. People may want to remind you of what happened in this company. When they do, you can feel really hurt and that those people are trying to destroy you.
Alternatively you can say to those people: "Look, I have learnt that it is wrong to bully people, that gossip hurts people and that it is wrong to threaten another person. Because of the incident I am now a better person. What have you learned out of all this?"
When you say that to people, they will look at you with respect and they will still talk about you, but they will do it with respect because you have learned and you take responsibility for yourself.
