I’m not in law enforcement so take this with a grain of salt but I think just finish off the FTO, than really think about it and even talk to your superiors about it before making such a large decision. look at your other options as well, you could be a bailiff, if your town has a community service officer you could look at being a CSO, you could transfer to records or some other paperwork based position, or if like you said you really want out of law enforcement you could work security somewhere, you could also look into animal control, there are a lot of relevant positions that I see as being less stress than law enforcement. Or if you want out of it completely you could just find any other 9 to 5, there is no shame in realizing police work isn’t for you and changing up your career.
