Need advice

Ok ladies, I've been in a funk lately and it's bothering me. I'm on the verge of tears at all times and I can't sleep at night no matter how early I get up. I don't work, I'm in college but I'm only taking 12 hours and my classes are pretty easy, but I still find myself worrying about them for no reason and worrying about everything else, even just worrying period and not knowing what I'm worrying about. I feel as though I'm anxious for things but I'm not sure. Is this normal pregnancy symptoms or does it sound like anxiety/depression?
