I'm addicted to smoking cigarettes
I wish/If only I hadn't started smoking
My computer has a virus
I wish/If only I had installed antivirus software on my computer
I've cut my finger
I wish/If only I had(n't)...
I've got a stomachache
I wish/If only I hadn't eaten...
I never learned how to bike
I wish/If only I had learned how to bike when I was a kid
I've got a sunburn
I wish/If only I had worn sunscreen
I've got a cavity
I wish/If only I had consumed less sugar
I've got a cold
I wish/If only I hadn't...
I've got a headache
I wish/If only I had(n't)...
I was late for my morning class
I wish/If only I had woken up earlier
I lost my house keys
I wish/If only I had put them in their place
My romantic partner left me
I wish/If only I had been a better listener
I've got a sore throat
I wish/If only I had taken my allergy medicine
I've burned my food
I wish I had/If only I had kept an eye on the grill
That movie was a waste of my time!
I wish/If only I hadn't watched it
I don't have any money
I wish/If only I hadn't spent it all on clothes
My child can't communicate in her grandparents' native language
I wish/If only I had taught her when she was younger
I have a hangover
I wish/If only I hadn't drunk so much wine
My house plants died
I wish/If only I had watered them more
I forgot my best friend's birthday
I wish/If only I had marked it on my calendar
I don't like my job
I wish I had majored in something different in university
I've got a twisted ankle
I wish/If only I had been more careful
I got fired from my job
I wish/If only I had come to work on time more consistently
I failed my English exam
I wish/If only I had studied harder
