A 2009 article about loneliness

What we call loneliness -- the feeling that you have no one to turn to, that no one understands you -- is a form of stress. And if it becomes chronic, it can wreak havoc on your blood vessels and heart.

"Someone may be anxious and lonely, or depressed and lonely, or having medical problems and lonely," says Jackie Gollan, PhD, a clinical psychologist at Northwestern University. Though one condition may influence the other, loneliness is independent and can be challenging to treat, Gollan says. "Even if you treat depression, loneliness may still be there."

Though depression and anxiety can certainly have a negative impact on your heart, loneliness appears to be especially deadly.

it's terrifying to know

I don't want to die. I mean I certainly have indulged in death fantasies but to really die? I don't want to. I can't. I mustn't.

It hurts and I'm so tired, I keep on trying and smiling and being nice but it doesn't matter in the end since I'm so disinterested. It's hard to express interest correctly when people take it the wrong way at times and it's infuriating.

I want to cry at times but I can't. I feel it edging on, coming but it doesn't, the tears stay in. I'm afraid of getting close and to be rejected or judged negatively by friends it hurts.

My sleep's schedule a bit messed up as well lately, and I do wish this wasn't the case.
