i guess i wont go into detail but i was completely alone for four years. during that time i developed mental health problems and negative habits that, at the time, i did not realize were due to loneliness. this was compounded by super bad stress from other things in my life. i reached profoundly low states of mental well-being -- looking back i actually am astonished. there is no doubt in my mind that whatever i encounter later in terms of loneliness, it will never come close to that.
after four years i met a girl and we lived together for another three years. the article hits the nail on the head about married couples -- having an so is the number one solution for loneliness. it turned my whole situation around and has left me off much better even though the relationship came to a sad end. if any of you guys are stuck being super lonely, i would recommend getting a girlfriend no matter the cost. also, i would recommend taking a complete multivitamin. something in those things makes my depression a lot better. good luck.
