A physical feeling you can get. Some people truly think it doesn't exist. Simply because they have never experienced it. It could be as little as missing their other half and waiting by the phone just to see a text or receive a call. In other cases, you can get physically sick over it. It's less common but it is very possible to actually throw up because of the pain. It feels like a major cramp in your stomach, perhaps a bad case of the butterflies. Some people end up not eating or sleeping much. It is a lot more serious that many people perceive it to be. Some are not able to come out of Love Sickness until they are really reunited with their love, whether or not they were actually dating. Love Sickness can be filed in through having a crush, being in love, having a boyfriend/girlfriend, being married, and it also can wash over you after a break up. Love Sickness is hard to cure and takes time and affection from others. It is no game.
"Hey bro whats wrong?"

"Emily and I got into a fight. Every minute I'm alone, the worse my love sickness gets..."

"Im sorry bro. Too mushy for me though man."

Love Sick (see also Unrequited Love)...best friends of the opposite sex who have known each other for decades but never got their crap together at the same time to “be together”. They know literally everything about each other, and have hooked up over the years (not to be confused with “friends with bennies”). They are each other’s “person”.

Love Sick becomes “Love Sick” when one party (often the guy) suddenly realizes he totally fucked up and didn’t marry their “person”, but married “bat shit crazy” instead.

Despite both parties now able to be together, the Love Sick person will have an epically dumbass reason why he cannot (the bat shit crazy wife he divorced but she won’t move out).

Love Sick usually gets totally honest with bat shit crazy wife, who becomes obsessed with “the girl”, making life a living hell for Love Sick with constant fights.

Love Sick becomes OCD with unrelenting thoughts about his “person”, interfering with his ability to do his job. Refer to movie AIRPLANE. Can’t land a plane.
“Why did I get married? I’m so love sick for this chick, dude! I can’t get her out of my head! “

“She’s single. You’re DIVORCED but won’t leave your bat shit crazy EX WIFE! Get your shit together!”

When you are so in love with someone that every single emotion you could possibly have is all wrapped up into one intense feeling.

You can imagine them, and you shake.

You can go days without eating anything.

Everything else fades in the background when you see them, and you can barely speak.

You feel like you have the chills, but you are really just wrapped up in love.
"I can't even think straight, because she is constantly on my mind. I am love sick."

The horrible feeling you get when your in love with someone who doesnt anymore, or never had the same feelnigs back. You cough and feel sick in your heart.
Things got crappy with the Girl, I was still in love with her, and she feel the same anymore. I thought about her all the time, and felt like crap, I got love sickness.

Definition #1.Being so in love that
you feel sick when your
apart from the other
person.
Definition #2.Sick of love.Being hurt
before and having very
little hope for it.
Good example would be
"So Sick" by Ne-Yo.
1."I feel so love sick when he's away
from me."

2."I am sick.....love sick."

1. When your so in love... not even living in the persons pocket is enough.. not even a half-an-hour pash cures the hunger...

2. When your away... and you never get around to ringing them.. and they also... forget about you... but you both know your in love... and its all so fucked up... but you still cant end it.. and if you do... you cant get them out of your head..

3. When you have your own special style of kissing, and touching.. and everything you do.. and you can never imagine yourself being with anyone else.. and cant stand the thought of them being with someone else
