i think somethings wrong.. what does this sound like it could be?

hiiii. im a seventeen year old girl and ive been having some strange things happen with my body over the past couple months. to start, one month ago, i woke up one morning and felt totally out of wack. i noticed something was wrong when i walked out of my room and into a wall and didnt feel it. literally, my enitre body was numb and i could not feel anything. when i focused really hard, i could kind of feel pressure but only like tingles. by the fourth day, i was not only numb and tingly but i was also having anxiety attacks and feeling totally detached?? this is very out of character for me considering i am a very very calm person. this lasted exactly 7 days. the only thing that i found could have been the cause was a spider bite on my leg. however, three days ago i woke up and the same detachment like feeling and numbness through out my entire body was starting again. this month, it only lasted three days, but it concerns my that its a bigger issue than a spider bite... does anyone know what this is?? im going to see a neurologist but i would appreciate any help before hand, thanks so much
