First and foremost, you didn't get injured.
Secondly, I think this is first post where someone manned up and admitted the crash was their fault. I salute you for that.
Now, your options: If you can find a car with a blown engine or trans that someone just doesn't want to bother to fix at the right price, it may be worth swapping what you have left and can use over. Or, you can part out what you have. There is plenty of demand for your engine and trans. If you need transportation quickly, you may be better off parting out what you have and putting that money towards a simple DD to get you around.
The decision is yours, and really depends on budget, time constraints, and availability of a recipient vehicle.
