Irritability and rage are most certainly known Effexor withdrawal symptoms.

"Anger – Do you feel like you are ready to rage? This is likely a result of stopping your medication. You aren’t able to feel as good as you did on the medication so your brain is trying to compensate. This may make you become increasingly hostile and a tough person to hang out with for awhile.... Irritability – Every little thing may get on your nerves or ‘set you off.’ Try your best to relax and control yourself around others."--https://mentalhealthdaily.com/2014/03/12/effexor-xr-withdrawal-symptoms-how-long-will-they-last/

"According to Richard C. Shelton, M.D., a psychiatry professor at the University of Alabama School of Medicine, there's a name for what I was experiencing: rage attacks. They most likely result from decreased production of serotonin—the neurotransmitter that SSRIs [SNRIs also affect serotonin] increase in the brain—which can lead to aggression, says psychiatrist Steven P. Levine, M.D."--https://www.glamour.com/story/going-off-my-ssris-rage-attacks

I certainly agree with your avoidance of provocative stimulation and news programs. There are some murder mysteries (books and TV) that are just too violent for me right now and I also found atonal, or music in minor key extremely bothersome.

It's not clear if you are still tapering. If you are, it sounds like you are going too fast. Usually when a taper is too much, the recommendation is to go back to the dose where you didn't experience withdrawal symptoms and stay there for a while before attempting another taper–usually to not such a drastic drop.

I tapered off very slowly from only 25mg, but had been on Effexor for 18 years. Six weeks after the last dose, I began having discontinuation symptoms. I am taking supplements (including l-tryptophan and GABA) which help tremendously, but when akathisia occurs, I've had to take Valium (prescribed for this).

Talk to your doctor about your rages. S/he may prescribe something to help.
