1 I just wanna use some italics...

I cannot, for the life of me, figure out why I can't use italics or bold! Am I missing something! Do they just not have it here? If not how am I supposed to do my internal monologue! *hugs knees to chest while rocking back in forth* I just wanna be a cool kid! Maybe if I get popular enough I could get a system! I just wanna use my italics! I need assistance!
