Hello mommies

I am 9 weeks pregnant and my last pregnancy was really good but this time I feel so sad and don’t like to do anything, I talked to my doc and she said it’s normal but I am not that person I was before. How long nausea will stay and how to be happy in pregnancy? I just became so sensitive and emotional all the time , my 5 years old is feeling sad too because he is not enjoying my company as much as he was before:-( what to do please help!!

TIA
