I tell him everything so that we don't have secrets between us

right now , i feel so uncomfortable. I feel like i'm coward stuck in somebody's body which is confident. I feel like i'm a 3 year old , i'll sulk if i don't get something , and this is not right. I don't think i'm at a correct age right now. I wear clothes that comforts me and i don't follow trends. I spend all of my allowance on mobile phone credit. But i don't care. I spend most of my times , online . And even my boyfriend , gets mad at me because i'm lacking of studying.
