I DON'T HAVE CONFIDENCE IN MYSELF?

I always have a fear that i cant be friend with anyone bcause nobody is on the same thought level as me. I am teenager but i dont think and act like teenager. When i meet somebody who look like very mean person or is very mean person, i get scared and be nervous and at that time, i feel that i am too week. I know others dont really think abt this problem and care abt more important things. But i always care abt this things and it is my biggest problem. I want to talk to others but when i talk to them, they seem like they are very uncomfortable to talk to me urmm so i feel uncomfortable too. People think i am not funny at all because i am not on the same thought level as them. When they joke abt something, i take that seriously. Do you think my friends are to much? or i am weird? i think so..
