Injections again!

Before I left hospital, a nurse handed me an injection for 5 days. I had an injection to prevent thrombosis every afternoon and I had to do this for 5 days at home by myself.

The nurse asked me if I know how to do this.
" I think I know and I can do this. " I answered.

" Ahhh, I have to do an injection again...... I thought it's over. " I thought.
This injection has a thick and long needle and it has oil base liquid medicine, so it was painful. I felt it took a very long time over these 5 days, and I felt a great achievement when I finished the last injection!

However I thought that I never want to do this again.
