Replying to Holy shit im starting to get old already

so recently i think my brain is starting to fail. i have no clue why but just recently i have become dislexic. like i actually have read something and thought that it said something else. i have quoted alot of posts on this site and gona back and realized that i read the post wrong. for eample, look in the "how would i do this" thread. i read eheaths post as i have been feeling this bank teller that is over 20, whenhe said, i have a feeling that this bank teller is over 20." so read my quote, kinda weird huh. and this isnt the first time ive noticed this. the the past week ive been misreading alot of stuff in a dislexic way. i am 17 and have never had this problem before. is it possible that this is just exhastion, stress, or sickness, cuz ive had a terrible cold for a coupld days? or am i actually going crazy
