Normal isnt normal

I've had this weird realization about how things that are "normal" just don't really seem normal at all. Like wearing the clothes that you like, changing the colour of your hair to the colour that you like. I find these things so unrealistic, and unattainable. Simply because I think of how I will feel now and how I will think how dumb the way I felt back then later in the future. So it's like I don't allow to really accept my "feelings" cuz to be completely honest they just cause me great discomfort, wether they be good or bad. I feel really weird and I always try to think objectively in every situation, but fall short everytime. And so I retreat to this cycle of over thinking about the past and hating those moments that I felt anything. Am I crazy or something?
