Hi and welcome and this is the right place to post.
You really do need some medical help. No-one is going to put a needle into you if you don't want it but you have to let the doctor know about your symptoms such as vomiting blood and withdrawal symptoms when you are sober.
Withdrawing without medical supervision can be fatal in some cases. Please get help. You can't do this on your own.
Ireland truly is a beautiful country. I am of Irish heritage too and have been privilidged to visit there. Perhaps you will go to Cork one day to. You can have a truly rewarding and fulfilling life beyond your wildest dreams if you get sober.
Take care.
