I felt like this like I was robotic and was a zombie. Like I would go through the motions of things even parenting but it was like I was outside my body watching everything and of course everyone liked me like that I wouldn’t fight or anything I would have a dumb smile on my face and just be there. I couldn’t live like that so I went to the dr and they lowered the dosage and that seemed to help and eventually I went on something else but it’s been awhile.
I was on a much lower dose and felt this after I'd been on it for about a year. Its the reason why I weaned myself off it.
I would definitely talk to your doc but maybe just lowering the dosage? Coming off an antidepressant and going on another one is a whole host of side effects and some you have to wean off of and you can't go cold turkey.
