Check engine oil pressure light on

[Sease]

I have a 2010 Cadillac srx with 96+ thousand miles on it.  Last night on my way home from work the check engine oil pressure light came on in the front center console in big white letters.  I just had oil changed about a month ago by our " mechanic ".  My husband checked the oil and it is not low.  And when I was driving home it seemed to be running fine to me. But today it seems it doesn't start right up. 

I just bought this car about 8 months ago. Someone please help me. I wont drive it. Can my motor be messed up?

It needs to be determined whether the message is a false message or a legitimate low pressure condition.  

Which engine is this?

When you started it today, did it still have the low oil pressure message?  Explain what you mean by, it doesn't start right up, did it start?

If it still has the message, I would have it towed to a shop in order to determine if this is a legitimate message or a false message due to a bad oil pressure sensor/switch.  

If it has the oil pressure message current do not drive the car, have it towed, to avoid engine damage in case it really is low oil pressure.
