I don't think anyone has any idea what to do after graduation. I also had that feeling of "waiting for life to start" which is a bizarre feeling.

Just try and keep your chin up through it all. You'll figure something out.

Well, you are entering an in-between as with graduation one thing is over and the next has not started but there is nothing wrong about takeing your time to look around to find a new bearing

You should celebrate you graduation, you have really achieved a major milestone that not everybody has.
I'm sure you will explore all your option and opportunities and find something you like to spend time with.
Just keep happy and don't worry about tomorrow so much.
