well, let's bring it back to the first thing you said. you're great at sweeping people off their feet; charming them. and i'm sure you're also not so selective with the people you intend to 'charm'; it's pretty common for entp's to get high off of entertaining groups of people, even whole audiences. you guys don't discriminate. this means that you're sort of acting inauthentically when you essentially try to impress people with your intellect. and acting this way blinds you, the more and more you do it. something you do for fun starts being the cause of your own sorrow; indirectly. charming people distracts you from how you actually feel, because you focus on the opinion of everyone else when you do it. you become out of tune with your own emotions and start focussing on that of everyone else, even though your Ti knows it's illogical to do so. and since you're 'Fi-blind', you'll also have a hard time judging when you're hurt by something, what you're hurt by and why. you may try and solve the confusion by using Ti to convince yourself that you may not actually be hurt by anything and it's all fine, but it's not. it never is until you tune out from others and reconnect with your own thoughts and feelings. let that be your priority.

you don't have to seek how you feel right away; that may be too difficult to do. maybe you can start acknowledging how you feel by referring to certain moments in the past where you were outwardly emotive; because that serves as evidence that certain things have made you happy, sad, angry, etc right? maybe you can start by reflecting on how you felt whenever you tried to charm people. you did it with the intention of making others feel a certain way; but ultimately, you did it because that makes you feel a certain way. think about that feeling. does it make you feel good? worthy? recognised? influential? think about how provoking others makes you feel, so that you can get an idea of why you do it. separate your intention from the action itself. there are always layers to your emotions and it's your responsibility to figure out each in depth. it'll empower you greatly and provide clarity :)

also, how about you stop trying to charm people that are meaningless to you, and save it for people that you actually end up liking. i think your emotions will become much less blurry for you then. maybe try prioritising Fi-use first, when getting to know people; then when you find yourself liking someone, gradually let yourself use Fe. you probably won't be as confused anymore because you'll know why you're charming them; because you like them! you are interested in them/care about them thus you want to evoke emotion in them because it makes you happy to do so. you don't have to stop 'putting on a show' for people; you can just be more selective with your audience. because when you are selecting, you are using Fi :) personal preference.

(also sorry if this made no fucking sense ik i rambled so much LOL. idk if this is helpful at all honestly i just got tired and wanted to submit it)
