Could this be epilepsy?!

Hello- I am a 22 year old female. I am looking for advice or tips from anyone who may help.
Starting 4 months ago i began to experience weird symptoms such as feeling as though my world is unreal and feeling very out of it, almost "high".... these feelings have been everyday. The one thing i experience that I think might be epilpsey because i will be feeling normal having a conversation with someone then all of a sudden i get this crazy rush of fear and i feel like ive just been drugged and then i cant remember what happened about 10 minutes before that rush... the memory is just GONE.. then i feel really messed up for about 20 more minutes then im back to normal. Its really strange....This happens about 4 times a month but im still left with the weird detached feeling and " high" feeling, but it gets MUCH worse during these strange episodes.

Ive been to my doctor and he seems to think it is aniexty but it doesnt feel like aniexty anymore it feels like a serious condition, i am going to the hospital tommorow in hope for some answers....

thanks for reading...
