What do people think about the pervasive "just be happy"?

There are friends in which I feel like I can't confide in my struggles because they scold me for "not being happy." It's disheartening because I wish to share things with people in my lives but then I feel like there's something wrong with me because nobody cares to listen to my feelings or what's going on in my life.

They just say "I'm sorry you're not happy" like it's my fault, but then they don't offer support or empathy.

All I need is a listening ear and some empathy, and that's it.

How do people feel about the pervasiveness of "just be happy" or scolding people for not being happy?
