27 weeks... Horrible Anxiety!!

Kat • Pregnant with baby #3
So I've been having horrible anxiety lately about everything! I know I'm stressed out about things.. My husband and I are in the process of buying a house, we own our own business and it's been slow lately.. It's just been stressful! And on top of that a good friend of ours passed away. It's just a lot going on and I'm trying to stay strong and not stress because I know it's so bad for me and the baby! Is there anything I can do to help with my anxiety.. It gets to the point where I have little panic attacks and can't breathe. Any tips?! ?
