Stop overanalyzing everything

I am probably the biggest analyzer, worrier, overthinker, extremely paranoid person out there and i wish i wasnt. Last week i spent my spring break in boston with my cousin and she kept telling me i analyze everything too much i overthink and blow things out of proportion, and she isnt the first to tell me. I just want to stop this!! Its ruining my life and potential relationships with people, but its not something u can just switch off it is a big part of who i am. i believe it has alot to do with confidence at least for me. If i wasnt so worried about what people think I wouldnt analyse every little thing they say or do. I know that i will never stop analyizing evrything and im not sure id want to stop because it is as i said a big part of me. I just want to get it under control and not let it be an obstacle in my life.
