Hey Sushee I am a hairdresser and these are some options you can go for:

Cut your hair into a v at the back so it still looks long but alot of it has been cut off and really layer and thin it..

I definately like the POB idea its quite common now I would start off with the longer POB first then get shorter..

Or you can go the Katie Holmes Bob which is really texturized and short

There are soo many options there is a hair site I will have to remember the name of it you put a pic of you on there then you can choose from a variety of styles and they syncronize to your pic so you can see what they look like
