i need to belt up and i am a joke present

A friend said to me that I  just  need to belt up. And stop going on about it and BE  the life and soul of a party   now .  I need to  stop living in  the past and I  think I have  come  to the conclusion I want to  start again. And Not just have to start again   But I WANT to start again. and I need Someone else to share it with. because like team work things are always so much better shared and it is like presents, which it is always so much better giving them than receiving them.  not that I am at all equating my new life as being some sort of  present  except perhaps more of a joke present  or a gift by  a friend who loves  to play practical jokes
