Stuck for 2 days

Hi...I had the Surgery almost 2 years ago and on sunday I got stuck like at 10 am... since then I start to vomit because this thing in the throat didn't want to go out and any of the things that I drink or eat could get to my stomach. Yesterday I decide to go to the emergency but I didn't have any help because the emergencies are full all the time. Today I stop to vomit and I could eat soup only the liquid. My question is, yesterday at the end of the day the vomit turn black.. it was something like coffee.. Somebody told me that it was because of the little heads of the vains that could brake and this is like the blood. Any body ever experience anything like this... Being stuck for 2 days and I feel like...terrible... Anybody can tell me, I try to contact one Dr. here but he didn't want to make any appointment because It wasn't his operation. Can anybody tell me if this happen before? (Sorry for my english)
