Prisoner of my own mind

Some days I think I'm batshit psycho for engulfing myself into scenarios that has yet to happen and emotionally investing myself into things that do not even exist. But sometimes, these gut-wrenching feelings are induced for a reason and in retrospect, I was never too far away from my imagination in the first place. Now the question lies, is this really happening right now? Because, just like in video games, there are many routes and if done right, I can dodge the bullets and become my own saviour. Have I already fallen in too deep? Why do I always have to live in paranoia?
