lonely?

"Try to be alone sometimes, it makes you realize where you stand in life, and what you are to others. It will strengthen you to face loneliness."

saw this tweet just now and i thought, is this useful? sometimes being alone means thinking a lot, and when i said a lot i meant a whole lot. besides, when you try to be alone, people might get the feeling that you're pushing them away and because of that, they'll leave. seriously, i've been alone for so long, i forgot how it actually feels when you have someone who's true to you by your side, even if it's your best friend. i lost my one and only true friend three years ago and it felt that i've lost everything. how do you think this will ever strengthen me to face loneliness? *sigh
