Struggling to breath to where its making me sick

I am having such a hard time breathing. I know its LO pushing on my diaphragm. Is there anything I can do to help ease it? I can't eat because there just feels like there is no room and when I do eat something I end up just throwing it back up a couple hours later. I never really suffered from morning sickness. Is there something to do to help ease this at all? I try rubbing top of belly, stretching arms above head. Any other ideas? Please help. ☹ 32 weeks.
