The problem with me is that I can't see any point/meaning in the vast majority of things. I also refuse to waste my essentially short life on pointless activities.
It goes as follows:
Is there any point talking to that slightly boring girl in the lunch queue if we're both going to die in 80 years anyway?
Is there any point in making new friends if in a couple of months they will realise I am an essentially boring person anyway? (This has already happened in a large number of cases).
This pointlessness never used to bother me. I blame philosophy.
(Note the presence of my lunch-queue hate)
