currently tapering; should i go back from 2.5mg to 5mg? feel terrible

hello i was on 10mg lexapro for about 8 months for anxiety, 26f

felt it wasnt do much except make me sleep all day and numb me, and it didn't make anxiety attacks go away like i wanted so i started to get off of it

10mg to 5mg was no problem(took two weeks in between 10mg->7.5mg->5mg), but since dropping off to 2.5 its been hell. i've been on 2.5mg for about two and a half weeks. i thought i had the flu the first few days(felt feverish and was on and off sweating/freezing) but that faded shortly. now i don't feel physically ill but i feel mentally terrible. constantly on edge, getting irritated by anyone talking to me, brain fog (causing me issues forming sentences, typos while texting, making me clumsier, just cant think straight), i even had a meltdown in the grocery store the other day because i thought everyone was staring at me and judging me and i started to cry and hyperventilate. i genuinely was never like this before the lexapro or during the lexapro until i hit 2.5mg.

this is even my third time being on it, and the last two times i got off of it i had no issues! i'm just worried and not sure what to do. i don't know if i should hop back to 5mg since 2 and a half week is already a good amount of time and i don't want to restart the whole process.
thanks to anyone who can help. of course i cant see my psychiatrist for another few weeks.

sigh, it would be reassuring to just even hear that other people have gone through this so i'm not worried about it being some other issue like early onset dementia ahahaha........
