15 weeks and just started throwing up ...why?

they said the 2nd trimester is supposed to be amazing cuz you get more sleep...

they said you will have so much more energy...

they said nausea will go away...

So why do they keep lying to us because I hardly threw up in my first trimester and now I’m throwing up way worse. Still tired. Still waking up to pee at night and still feeling overall blah 😒

Please tell me I’m not the only one. Wth. Also my doctor is useless and literally told me nothing about what to expect.
