I am filled with anxiety and depression and sadness when my girlfriend told me this, what do I do!?

I was told today by my girlfriend "I love you" in public and we've only been dating 1 week. I feel like my mind, soul and body has been split in half and my true self has to choose one half to continue on with life. I'm not sure which way to go. The way with the golden chariots filled with adventure, or a life settling down and not going on an adventure around the planet. Theres no signs telling me which way to go, love or no love. Which is the answer. I don't know! I wish I knew the pathway to go, so that I can calm down and not worry about it again. Which way do I go!? How do I know if your right?!
