My boyfriend and I broke up

Last night my boyfriend broke up with me. Things were sorta complicated, so Im not going to go into depth. But it caused me to sob for hours, and when he left I felt sick? I threw up a couple times, and now I feel that lingering urge to puke. Its almost the same feeling as being hungover. My eyes are extremely puffy and red, and they hurt. Are there any tips to make myself feel better physically and mentally.
