After effects crashing

I spent hours on an edit and it suddenly crashes, at first I didnt mind all that much until I realized that It didnt save. It wasent in the auto-save folder I had, It wasent anywhere. Obviously I was devastated after working so hard and wasting so many hours just for all my work to disapear in mere seconds, please tell me I can get it back. Please help me, how do I get my project back?
