i am a Chartered Acoountancy student..i graduated from high school in 2013...since childhood i was made to believe that if i study hard and get good grades i will get everyhting i want in life...good job..RELATIONSHIPS,friend circle etc..i was made to believe by my parents that studies are the only thing that should be done in school..and as gullible as i was..i completely believed them..i worked hard in studies.and as a result became nerd..i never made any friends.never went to parties..after 3 years of graduating from school life.i still have no clue as to how to sociallise..how to make new friends..i feel completely hopeless now...our course demands regular study.since its a open course we have no college life..and for virtually my whole life i never had any fun..never went to hang out with friends unfortunately i knw bettr nw..while studies do get you good job..does it really help you in personal life also???i was made to believe it and got hurt when i faced the reality..now i feel demotivated to study..i still have no social circle..no social life..no friends at all..just home to office and office to home..my office collegues are all seniors and fake so i have no firends there also..is all this stuggle worth it??i feel very nostalgic..i feel i should have not known this bitter truth until i completed my CA degree..now i wonder whether all this struggle is worth it??i always craved for good friend circle because i was always lonely from the childhood..now i feel trapped
