I hope the sacks help you, but I have to say that I hope you don't try to give the shots yourself. I think it is possible that you could stick yourself a second time as I know that in spite of giving hundreds of sub-q fluids and injections, I'll still sometimes scrape my finger with the needle as the cat does an unexpectedly sudden buck and twist. A second shot could put you in anaphylactic shock and I don't think your father is in good enough health to keep you alive while waiting for an aid car. Good luck!
