I’m so sorry for your struggles with discontinuing an SSRI. Hang in there as it will get better.
I am 70 years old and have been prescribed Paxil (40mg) for 15 years. My depression is serious and Honestly it was a life saver! Last summer my physician let me know that studies indicate this drug could cause - or worsen - dementia and it was time for me to stop. I began researching withdrawal side effects and was not happy as there were horror stories.
My MD wanted me to decrease by 10mg for 2 weeks then another 10…
I insisted that I would take it much more slowly starting with a 5mg reduction for several weeks.
I read one story where it took someone a year to completely discontinue an anti depressant so I felt encouraged by that.
My point is just that - don’t rush! I am down from 40mg to 15mg and feeling good. It might take 4 or 5 more months to complete and that’s okay.
Good luck and just know you are not alone.
