Lady ... do you have another device, say a phone that is synced to that gmail account? If so take the device and immediately disconnect it from your, or its, internet connection. There is a chance that your draft was synced or part synced and has yet not deleted if it syncs with your main account as you open it. Remember first thing you do is disable it's ability to connect to wifi or mobile networks. Do not open gmail in it before disabling the connectivity if you have a second device.
