wrong injection for the patient

Hello everybody,
thanks so much for all your support. it really helped me to feel better at least regarding the error itself. The first days I beat myself up over it all the time and thought I wasn't even worthy of calling myself a nurse anymore.
The country I want to go to is Australia.
THe situation is not any better... I am not getting shifts by my agency and I feel like someone is holding me under water and not letting me to breath. THe consequences are horrendous. I contacted the nurses union and they said this incident is not a reason for my agency not to give me shifts in other hospitals. In this case I believe it's all about keeping reputation (of agency and hospital). Reputation of the hospital: The patient and her husband are both working for the healthservive executive and appear to be quite high ranked there. The husband keeps on inquiring what happened to "the nurse who gave the injection" and it seems that he wishes me to be struck off the register. The hospital though didn't report the incident to the nursing board as the outcome of my error wasn't severe in any way. So now when the husband asks, the hospital says that I'm suspended and he will be happy to hear that. NOw regarding my agency. They are a rather small agency who works only with 4 hospitals. ANd if the hospital where the error happened hears that I'm still working for them it will throw a bad light on them.
The punishment is so much more severe than I ever believed it could be... And my livelihood is about to be destroyed.
I contacted the nurses union over this and they will handle the matter. I hope the storm will be over fast, otherwise I'll be on the street without any income.

well i was warned to apply anywhere else because they said they will have to tell the next workplace that investigations are still going on in my case... Here in ireland nobody would accept anybody who has investigations going on so if they arent being closed today I am in big trouble financially. They said once the investigations are over things will be easier... but nobody knows how long this will take as the husband of the patient is very very angry. So now the situation is: Public hospitals dont recruit, private hospitals ask for at least 2 years acute hospital experience (i have 8 months exp, of which 5 months are nursing home which doesnt count for them as experience, and 3 months agency nursing experience) So the best thing to do is to join another agency but they will inquire with my current agency and will find out about the fact that investigations are ongoing on my name. They wont bother accepting my applications so i better wait another few days before i loose my chances with those agencies. I am now waiting for a call of the union regarding what to do.

thanks for all your replies.
The "investigations" are still going on, i am still without income and i am not doing well.
i started to have panic of the day when im supposed to return to work. I frequently wake up in the middle of the night, my heart is racing and am fearful, thinking of work and the possibility that i could do a mistake again if i get back to work. Over day i am anxious and depressed, i cry many times a day. Its eating my bones. MOre the fact of that im still without income, the fact that i fell from the upper floor (everything went soo great) into the muddy basement within a blink of an eye. I feel so ashamed also towards my colleagues. People will say that i might overreact.. but the past 11 days turned me into an emotional wreck with panic attacks and i feel treated as if i killed someone

I REGRET THE DAY I PICKED NURSING
