I am concerned as I collected some unemployment benefits I should not have collected.?

I lost my job well over a year ago. I have been unable to find work in my profession or any profession. I am now in the process of losing my home, had to file a Chapter 13 bankruptcy. I have been collecting unemployment benefits but lied for two months when I got a job out of the area that I had to commute to each week (270 miles round trip) and pay for a hotel during the week. I really needed the extra money to still pay the few bills I had and pay for the hotel room and gas. I was hoping the job would work out but it didn't. I know what I did was wrong; I have never done anything illegal in my life. Now the unemployment insurance office is scheduling an interview with me. Could they have found out about my two months of work....what do I do and what do I say during the interview. My mental state is not good. I feel all has been lost. I can't believe I put over 30 years in to an industry that is in such turmoil right now. I made alot of money in years past and spent it. I never worried about the future and now I know I did something wrong. How do I answer their questions....what if they penalize me and I don't have the money? Please, I appreciate any answers anyone may have. Thank you.
