I've always felt that I don't belong in this world, is this normal?

Thanks for your thoughts/stories , it's been comforting reading them , I have since I remember knew I was different I used to think of it as a bad thing , because I felt , was different from the other children I got picked on and looked at and treated differently my parents weren't a match at all don't know why they stayed together for that long , so that made me feel even more different when kids played and be silly other parents would laugh yet I was totally aware of what silly was /is when parents came to you and went aren't you cute I would think "do you think I'm stupid I know what your doing " as young as 5 so I seen the bad the ugly of life most of it up to now I'm 28 ,, even though I was nice I wasent confident and ppl seen that and preyed on me , even teachers , bosses , colleagues , untill my 20s, I can see through the world somehow , through the lies and manipulation , people playing the game to me life is like playing theme park world I'm aware but everyone else isent aware to how they are manipulated and how fashion , and everything else can change when they want it to , even now I have friends nice friends and know a lot of ppl now , I still feel like I'm acting because the world is a certain way I'm able to see through it all , (dont want to make it sound like i feel like I'm better or nasty it's just how I feel ) , I be honest I don't dream of another world I do feel like I can relate to people that are fictional because this world doesent feel real to me , I'm bored , sitting there having social occasions and in a way it's like I'm being fake or acting because I carnt be my self. Its like everybody in the world are being played and I have to act because I'm aware ,,, society has deemed me not worthy or wrong , freak , because I like being nice to people , helping people , smiling , I don't wonna go round shouting abuse , or talk about my addidas trainers or where I'm going on holiday trying to show of to people without making it obvious , being nice is a crime but if you can bully or overpower people with your personality , or make friends to stab people in the back to benefit yourself and take advance of drunk women and abuse them then if you carnt do them then your not worthy .. If this is the world and it's message then beam me up Scotty get me the hell out of here of this joke called a life . But that's negative I don't want to think like that I don't most of the time I understand you live once so I try to be positive all the time , even though I am abit spiritual I do believe we have a reason there had to be maybe we are special I really believe on the level of thinkin we have I really believe we have to do positive things for the world /ppl ,,, I beloved there is a reason really do , you can sit at home and mope why am I like this and not everyone else , I wish I was normal , I wish I was someone else I could go on but , we are on a different Lvl of thinking deep thinking that means we have the means to be very good at something , don't you know you have a reason but not sure what took me along time to find out what mine is I'm doing courses now to get there , my reason and I be even happier when I get there. You has to be happy , deep thinkers have to potential to be very successfull in life , just look at the smartest ppl in the world , anyway I hope this helps someone in my world of thinkers , thanks for reading take care
