pondering

is it normal to have second thoughts about what you are about to do? i am having seconds thoughts on going to do Jaw surgery to correct my jaw misalignment,however its only just a slight misalignment but i cannot turn back now. Since ive decided, ive to stick to it. Besides the orthodontist has already extracted two of my teeth. Sigh. am i making the right decision to even go for the Jaw surgery? And i suddenly realized that why my orthodontist pluck out 2 of my teeth?! Shldnt he jus pluck 1 out since he is just gona pull my other teeth in line?y must pluck the other? Gee! It is all worth the pain for what i want? Gee..
