My advice, grab a movie and go through an adventure with the characters. It helps you forget about your loneliness. I'm always inspired by great feature animation, movies, or any story really. I like stories about struggles, I think all INFJ's can relate... so that's why I enjoy watching movies (especially pixar!) about characters experiencing a struggle and overcoming them.
A more long term solution is that I've set some goals for my life and pursue them. Find something you're passionate about that doesn't rely on another person's response/attention span/reciprocation. If you can pour your heart and love into your work while keeping your life open to the people you meet along the way... you'll turn around and realize you weren't alone after all.
Truth of the matter is... you have ONE consciousness. We are alone in our minds... but we are not alone in our communions; only if we lock ourselves away from those things and only if our consciousness refuses to enjoy those moments that are shared.
I think a lot of our feeling of loneliness sometimes stems from an inability to experience the 'now'. I don't know that it's introversion? Or maybe it is...
We withdraw into our minds, disengage with people (especially in social gatherings), and begin to self-examine or analyze our situation. While Suzie and Joe are talking about the baseball game with us at the barbecue, we're standing in-between thinking "baseball... is that all they can talk about? Gosh.... this is so stupid. I want to talk about something deeper. I want to find my soul mate... I can't do this... god I feel so lonely right now" and thinking millions of thoughts per second .. feeling lonlier and lonlier while Suzie and Joe are having a great time connecting (they can probably taste the barbecue sauce burning in the air but we're too busy in our heads to notice how delicious barbecue is.. I mean honestly, it's DELICIOUS!). Suzie and Joe are enjoying the 'moment' for what it actually is... a moment, a fleeting moment... a fleeting moment that if we don't appreciate, we lose it. When you lose it, you feel even lonelier. It's a cycle.
I use to be exhausted going out and meeting people because my brain was doing a million processes while everybody else was probably doing 1% of that. I burned out easily (mentally) and all I did was stand around. It's silly really! Let go of your mind, pour some ice on the CPU, don't take it so seriously, relax, be a little care free.... let the situation flow naturally and if it ain't happening lets leave. Won't be so tiring if we approach the situation by allowing the least amount of mental trauma :laughing:
I've learn to curb the lonliness that I experience with my friends by switching my focus from my mind, to what's going on.. If we're out to eat, I'll close my eyes, taste the food. Imagine poloroids of the places the food may have been eaten.. Paris, London, France. Smell the dessert, experience the moment with your senses.. eyes, nose, mouth, ears. Don't block those things out, they're there for a reason. If we're too stuck in our heads, life seems colorless; but sometimes it's hard to see the colors when all we see is our thoughts.
(I'm in a totally different mood so my answer probably seems like it's coming out of left field.. but hey, I winged it anyway.)
PS: I feel like I'm in a good place in my life right now. Things aren't so rocky. I've just spent the week... alone. But somehow I feel great. I feel loved? Today I feel loved and I can't explain it LOL I just feel good. There aren't alot of days when I feel this way, but I think I'm just excited about my future and career LOL
