You can relax. We're already in end times so what you see is what you get.... No multi-headed monsters rising out of the sea or giant insects with human heads flying around.
What we have instead is a bunch of governments all over the world who don't believe in God and are promoting atheism and godliness. That is our end times right now. All you have to do is try to make a decent life for yourself and don't worry about such things. The monsters in revelation are most likely just metaphors for worldly things like diseases and governments. We already have all the other end times things going on right now in the world: widespread famines, disease, wars, christian persecution, etc.. For all we know the worse is probably already here, so just relax and try to enjoy this life that God gave you.
