I don't want to go there but I go there all the time so it’s like a Catch-22.

fy: 我不想去，还老是去，就像掉进了第二十二条军规自相矛盾的荒诞陷阱里。

实际上就是指荒诞，没有逻辑的，自相矛盾的情况。鉴于翻译者也有介绍西方文化的义务，所以这句的翻译最好第一阐清含义、第二保留原作表达法。

Catch-22

A no-win dilemma or paradox, similar to damned if I do, damned if I don't. For example, You can't get a job without experience, but you can't get experience unless you have a jobit's Catch-22. The term gained currency as the title of a 1961 war novel by Joseph Heller, who referred to an Air Force rule whereby a pilot continuing to fly combat missions without asking for relief is regarded as insane, but is considered sane enough to continue flying if he does make such a request.
