Anxiety since pregnant.

Savannah • 18, expecting my first bundle of joy! Taken since 12/26/14
So lately I've noticed my anxiety has gotten a lot worse. My bf wants to go to his buddies house to take the motor out of his old car to scrap it great idea BC we could use it to pay off some debt and I told him that he says okay I'm gonna go do it but I never want him to go anywhere I don't want him to leave me alone in the house he always says for me to come with him places I just haven't felt like it lately. Its like ive become this leach that doesn't want him to leave and this so isn't me. ?? I just want him here at all time and then when he's gone I'm counting down the minutes till he's home. Why am I like this? I've never been like this???
