"I´m so excited...."

"and I just can't hide it...."

Today when I woke up and greeted the parents in law, they saw my silly smile and commented it. LOL. Well what to say.....
Forgive me for being excited?
Forgive me for being happy?
Forgive me for not hiding it very well?
Or I think the most appropiate would be:

Forgive me for my lower mood the past 2 months!

Well Iam missing you and it's difficult being without you.
Nothing is motivating me.
I need you!
