<human>: Can you provide a brief rundown of the text in within 3 sentences?

Hey reddit, apart from working a little for my mother's company, and doing full time volunteer work (current), I don't have employment experience. I quit university after first year last year, and spent nearly a year doing very little. I recently applied for a Summer outdoor instructor position (equivalent of like $11 an hour). Anyway, I got an interview. My main fears are that I stated I was out doing landscaping work over Summer, when it was actually the previous Summer. I also stated I worked in the family office for 2-3 months, when it was actually more like one month.

The only way I can see this being unravelled is if the interviewer talks to who I volunteer for (who I am very friendly with and I told them I basically did nothing) and asks them about my previous experience. Should I pull out of the interview? Tell the people I volunteer for about my 'fib'? Don't worry about it? I know it's not the largest of lies, but I basically filled in a gap of inactivity (one I can't explain really, I was stressed and a bit depressed from university burnout) with exaggerations and small lies at my mother's suggestion. I'm now quite paranoid. Can anyone console me, or give me the harsh truth? Thanks reddit.
<bot>: said on resume I worked during Summer for family company, but didn't, and worked the Summer before in actuality. Spent like 9 months doing very little. Got an interview. What do?
