It sounds like your bloodlust meter is too high. Any other states that take control away like that will wear off after a battle, if not within that battle. But the bloodlust ones will linger until you reduce that gauge. The easiest way is simply bathing or using cleansing water which the standard item shop at the camp sells.
Do let me know if that DOESN'T fix it though as then it's definitely a bug of some kind that I'll have to look into.
