How do I get my electricity to work in my room? I did something wrong. Help!?

Sounds like u tripped a breaker or blew a fuse.1 get the right size bulb for the lamp.2 find the breaker box ( if fuse replace it,if breaker find the one that is tripped and flip it back on) with the right size bulb in the lamp plug the lamp back in,in the event it does it again repeat step 2 and replace lamp.
