Forgetting words and things

I'm bilingual and english is my second language. Before epilepsy, I used to have a wide vocabulary and my english was also pretty good. But now I even forget the meaning of words of my own language. Its pretty irritating tbh. My memorization power was very good and I used to take pride of that. And now it all seems to be good for nothing.

I also forget things from little to big. Sometimes I'll just tell things I have already told people a few times before. I'll forget important tasks and dates. It doesn't even feel like I am me anymore.
