I would guess istp but you sound heavily biased in order to get certain results haha. Although you are emotionally apathetic, it doesn't necessarily mean there is no Fe/Fi (although it's less likely). Fi users can sometimes be that way, as the function is more about values/morals rather than actual "I'm gonna do this cuz I feel like it", as a lot of people mistake it to be. It does sound like you have a lot of Ti and Se, but I'd suggest you take a step back and try to look at things more objectively. Also keep in mind that mbti is a tool for growth, not for identifying a certain way and pushing those habits to the extreme. Hope that helps, best of luck!! :))
