Hi Toots, wow, that's a tough one. I'll second what Edz said - don't think this is the end unless you want it to be. As far as your response, I wish I could offer some words of wisdom but I'm not sure. I'll just say - don't feel pressured to respond right away. No harm in leaving it till the end of the day or tomorrow, and taking some time to really think out your response.
Perhaps if you need to buy time you could reply "so sorry to hear about your job. [something validating or encouraging] Wow there's a lot to think about in this email, I'll reply properly tomorrow."
