I'm scared and worried, how if i wear coloured contact lenses even i don't need them and just for style.., is it safe?and what will happen to my eyes?

Can be safe: These contacts can be safe if fitted properly and taken care of. Most likely nothing will happen to your eyes, except for a little dryness maybe.

Some are unsafe: The colored contact lenses that are uniform in color are probably safe if prescribed by your eye md, but those that are made up of little dots of color and can just be ordered online can create very important eye problems. Discuss this with your eye md.
