I Don't Know

I knew I was about two months behind on getting an oil change but I figured I would take care of it after I got back.  There were never any leaks or stains under it and the oil light never came on.  Last night I was on the highway driving back to my house from the store and the oil light flashed for just seconds, then my car died and I could smell burning oil.  I had it towed to my house and today I checked the oil and there was nothing.  I think I seized my engine.  I cannot believe it.  I know a car needs oil but I though that if it was low the oil light would come on and it never did - never.  I am screwed - I really do not know what I am going to do.  I do not know how I am going to pull this rabbit out of my hat.  I also am so upset with myself.  I was so stupid and really thought everything was ok and that if the light was not on then I had no problems.  Tomorrow I will know more but I really not hopeful - so upsetting.  But I am lucky I have my bike and can either ride it or walk to anything I need including my job.  That truly is a blessing but I just don't know.
