I always feel this way unless I have 1-2 special people in my life that I've really bonded with (the best friend, the boyfriend, etc). No amount of socializing & interaction removes this feeling unless I've really connected to someone & have them actively in my life. Even then, I will have bouts of this if I feel that person is distant at the moment.
It's funny, because, I know now that it is possible to make those connections, and yet, when they are absent in my life, I still feel like they're impossible or unlikely to ever achieve again. It seems others find them so much easier to make than I do, and so they disconnect much more easily also. I'm wondering, "Why are you not holding onto this for dear life? Don't you know this is rare?".
[MENTION=14216]RevlisZero[/MENTION] Are you really not typing as a 4 now?
I say that because the 4 often convinces themself that they are too different, too complex, etc, to ever be understood by anyone, to ever connect with anyone, and yet that is usually what they desire most. It becomes a self-fulfilling prophesy for them. If you want to connect with people, then you have to change your mindset; the behavioral change of getting out more is just part of it. Sure, anyone may fall into this thinking, but it's has the stamp of the 4 all over it.
