Alleged madness
The passage from Act 3 Scene 4 has the recurring idea of alleged madness. First, Olivia, Maria, Sir Toby and Fabian were all making Malvolio seem crazy and devil-possessed with his snobbery and arrogance. Then, the passage shows Olivia desperately in love, thinking she is like Malvolio--going mad. Lastly, Antonio's friendship to Sebastian ( who was actually Cesario) was introduced.

Happiness is an emotion. Just is regret, sadness, solidarity, grief, etc. In most scenarios happiness is an attributed factor and result of struggle, but not always.
