Baby is kicking my stomach T-T

Addah
So I really don't know what to do right now. My baby has kicked my stomach before, but never for as long or as hard as tonight. I started getting violently ill and over the last hour I have lost 5 pounds from my weight this morning, and despite having literally nothing left in my system i still feel so sick. Has anyone experienced this? I really don't know what to do if this happens again, because when I get ill I get violently ill and always end up losing several pounds in a matter of hours..
