It's also a question no-one can answer for you; no-one here can tell you whether or not you should bother trying again!
I don't know what the RT test is, is that now part of selection? Unless you've actually failed a part of selection then it's really up to you. If I had failed a part of selection, I would have followed the advice given to me when I failed; so if they said "try again in 6 months" I'd try again in 6 months.
You don't have to put the rest of your life on hold. There's no reason why you can't get a job (if you don't already have one) and start putting some effort into another career while continuing an application on the sidelines.
Whether or not you can be bothered because you think "fate" doesn't want you to join is a question for you though, not anyone here.
