Beside myself 

Extreme joy, anger, etc, brought on by a situation that causes one to be "out of one's mind" with that emotion.

"Beside" was formerly (15th through 19th centuries) used in phrases to mean "out of a mental state or condition, as 'beside one's patience, one's gravity, one's wits'" (Oxford Engl. Dict.), and that use survives only in "'beside oneself': out of one's wits, out of one's senses."

I was so beside myself looking at all the women on the beach that I didn't hear my wife yelling for help.

best buds 

A person who is always there for you no matter what! A person who you love to hangout with and feel you can do anything with without being embarssed. Someone you know that will always have your back no matter what. And you will do the same for them! Someone you can have in depth conversations with and know they will never tell!

Amanda and Amanda will always be best buds until the end. They will always have each others backs no matter what. Im jealous of them. I wish I had a best bud like that.

Best boyfriend in the world 

The best boyfriend in the world is someone who is always there for you when you need to laugh, when you need to cry, or when you're falling apart. This boy would stick by your side through everything and be your number one supporter, doing everything possible to make you the happiest you can be. He'll love you more than imaginable.
