I see.. Thanks for the answer!You will be fine.
I tried to max out my fitness as fast as possible and always lacked stamina at the end and as a result got corrupted by feet super fast and everything was fine. It was undaoubtedly worse then not having that but you can still resist normally when stuff happens, the difference is that for example you can give a girl water every day and she gives you a cookie, then afterwards she asks if you would massage her feet (to gain reputation) and you then can't say no if you are corrupted by feet, then it asks you if you want to resist or indulge and if you indulge you gain some mind and stamina I believe and if you are not corrupted then you lose both. I always resist because that makes it go by faster when farming reputation.
Just be warned that not being able to say no means that sometimes you will have to avoid some events if your stamina is too low since you could not refuse when asked and while you get some stamina back for indulging you still spend more for the massages or whatever you are doing and passing out is REALLY bad most of the time.
