This site is great for venting or distraction during times like that. The desire to throat punch somebody for creating idle banter will come and go for quite a while. Get accustomed to dealing with that. Just remember that coworkers, friends, and family are not responsible for the rage you are feeling. Do not take it out on them. Bring your rage here. We can take it. Need a target for it? I'm your huckleberry, if need be. Reach out if you need help, quitter.
