I Am 54 Years Old, Female, Menopausal, And Have Been

I am 54 years old, female, menopausal, and have been on Lexopro for anxiety for over 10 years. Over the past 6 weeks I have been weening myself off of the drug and am no longer taking this medication. For the past couple days I have been noticing an increasing dizzy feeling, as well as an inability to perform normal tasks at my usual level of capability. I also have been feeling like, when I turn my head, almost like a jolt of electricity is zinging through my head. Over the past couple of weeks, my balance has also been affected.
Could these all be attributed to my going off the medication?
