First off, I offer my sympathies as someone who has been through that you are describing. I have had more than my fair share, I think.
Second: probably obvious advice for that desire to lash out: if I know I’m angry, I’ll write the post the wait to submit it. Just come back in a bit. It’s become a habit.
Third advice for withdrawal: SSRI withdrawal effects are definitely a thing, and there are tapering plans that make it more manageable You can find the info and plans written by doctors–incluing ones that let you see the pace.
Yes, Effexxor is an SNRI, but that just means it has SSRI and NRI attributes. It still counts. If you’re having this much trouble, the pros would recommend going slower on your taper. ( And cold turkey is NOT the recommended way at all.)
Some additional info that may help: This technically isn’t addiction, because you’re not craving more of the drug. It’s tolerance. But you don’t have to be addicted to face withdrawal.
Your thoughts right now ARE NOT necessarily what the medicine was holding back. While some of it can be rebound (returning of old symptoms), tolerance means it can actually be worse. You’re also just feeling bad and possibly even sick, which makes thoughts worse.
My advice is not to think of this as what was in you, but how the withdrawal is affecting you. You are not your thoughts. It sounds weird, but it’s true. You can have thoughts that are inconsistent with what you value or believe. Thoughts can be symptoms, too. Meditation can be your friend–observing thoughts rather than han embracing them.
Sorry, this is getting long. My post was shorter until I reread and noticed the specific medication, and realized I had actual experience that might help.
I’m sorry you’re going through this. Please don’t leave, but also don’t feel any pressure to post.
One last thing: a small, occasional dose of ibuprofen would help me. I say small because you can possibly be a bit sensitive in SSRI withdrawal. Serotonin is a vasoconstrictor, and suddenly having less can mean blood vessels expand.
(On mobile, so apologies for my post being a bit out of order. It’s more annoying to edit, and I’m not feeling well myself.)
