when you are so desperate that you check your cell phone every 5 minutes, just in case your ex has called or texted you.

And guess what ?!!! she hasn't. she is just having a great time with another man or a group of friends which didn't get along with you,

fucked up in the head about love

Love sick means to want love. When you love someone so much, your whole world can revolve around them. Basically like desperate but not from that point of view.

Love sick can also mean to be sick of love. Basically like a clingy girlfriend. You get sick of it but you still love her. Your basically trapped in that situation.

the state of being tired of love, and the people involved in the feeling and/or act

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.
