I honestly have no clue. I've read this over and over, but I really have no good answer to it. I've felt severe feelings of loneliness, but I always fed into them until I exhausted myself. I wouldn't recommend that as a solution in anyway. Usually when I start to feel that way I will play that dance track playlist I have, and dance until it hurts. Somehow music provides this weird sense of clarity, and connectivity. It's gotta be the right music though.
Somewhat like you - and it's something I failed to mention in the original reply in the thread - I listen to the music when I feel down (I'm having a hard time distinguishing my feelings, so it's either I'm down, neutral or up most of the time). I lie down, put on the minor-mood music (the deeper I feel, the deeper the mood - I've classified them with three steps of mood in the collection) and think about what happened, or what I might do. Thankfully, I've developed enough of a self-repair mechanics in my mind to prevent myself from drowning into the self-beating thoughts I got so used to having; as I lay down, I help myself work through whatever I feel, and learning about my feelings - for which I have no innate sense and idea - helps me feel fine, bring myself back to stable.
