That was a terrible question, because you call someone who thinks they are ill all the time a hypercondriac. So as in Jeopardy, "What do you call someone who is constantly under the impression that they are ill?" Answer: "What is an a hypercondriac?" That is correct!

It depends if your crush knows you like him or if he thinks of you as just a friend or if he likes you too. If he knows you like him don't be annoying to him and call him all the time just occasionally. If he thinks of you as a friend just call from time to time maybe 1 time a week at most. If he likes you too, then let him call some too, other wise maybe 3 times a week.
Party animal or party doll
A best friend or a soul mate!
A know it all is someone who thinks he knows everything and refuses to accept advice or information from others. You could call then a pretentious boaster, one who intends only to attract notice and impress others.
