You are certainly not alone, jtbeachbum, as I myself experience these sort of emotions quite frequently as well. I'm currently going through this process when it comes to social matters, as in spite of other being's generally acting in a friendly manner towards myself, I still have issues deciphering whether these people truly appreciate me for the person I sincerely am or are merely being courteous and polite without genuinely meaning their actions towards me.
I'd like to be more serene and self-assurred, and yet this seeming negative force somehow prohibts the ability for me to feel confident and at ease while encircled by others. I'll speak of these feelings towards my mother, whom is one of those rare human beings I feel truly acknowledges the individual I am and bears unconditional love towards me without consistent judgement, and she will simply retort that I am much too young to be undergoing such emotional concerns and should instead focus my attention on more of age matters such as my schoolwork and merely finding my place within this world.
While I still tend to feel a bit distressed when it comes to my role within society, in reference to a post I read from another INFP within a thread I created recently, know that in spite of your profound nature and vulnerability that your way of viewing this universe is not incorrect, for the fact that you are able to both follow the indications provided by your heart and empathize with others solely means that you are unique. Whether you believe this fact or not, you will eventually be able to indentify with other persons whom share the same complex and percipient nature as you yourself, for your not being able to identify with a being whom for instance may be either an xSTJ or xSTP does not signify that you are bound to be an outcasted freak within human society, for it instead merely means that the people with whom you will sincerely be able to form a intense emotional connection with are still pending to be found by you.
Exemplifying an unfortunate aspect of my personality that I have had a bit of issues overcoming myself, please do not feel the need to consume yourself within melancholy and hopelessness, and refrain from believing you are of no worth whatsoever and will invariably be outcasted within this world of ours, as you are but another distinct individual residing in this cosmos whom has something to offer towards this crazed universe that no other human will be able to themselves in quite the same way you do. When you dwell within the grasps of fatalism, you are merely stunting your foresight and yourself from being able to transcend towards the direction in which fate shall lead you, but when you maintain your past dreams and are invariably able to refuel an unwavering fire within your prioritzed goals, believe that they will surely be made a reality on nearing day in which you'd least expect it, in spite of whatever length those fantasies need in order to be realized. Know that you are not the sole spirit whom feels in this way at the moment, and that in spite of the pain you may undergo with a failed relationship, that there will forevermore be at least one distinct soul or so who will appreciate you for the person you arleady are.
I hope I didn't go too overboard with my commentary towards your issue, by the way...I've always had an issue with getting much too carried away while typing something within my computer :blushed:.
