Cracked screen led to numerous other problems.

There is something wrong with my phone. In addition to the cracked screen, the mic & front camera are broken, I can't get cellular data, the screen has been moving by itself (sliding back in front b/t screens, opening apps, calling people). All this happened after I broke the screen. I have done no other damage that I know off.

Can my iPhone be fixed or naw? If so, what exactly do I need get done?
