HAVING to HAVE/DO something is sort of like a trigger of mind..
for example, HAVING to HAVE tomato sauce on spaghetti or noodles?
or, HAVING to DO everything a certian way or it isnt right -- wake up, pick out clothes, shower, dry hair, make up etc -- if its not done that way it seems the whole day just collapses, then goes back to thinking that because you did that little thing in the wrong place of something else that was the problem for the awful day.
someone i know HAS to listen to this certian song once a day, soon as they wake up and if the song isn't played the whole day falls apart.
is it just your brain telling you because you've broken routine that the day is going to be miserable?
