You're very kind and giving Chihuahuachic. 
But please look after yourself first and foremost. 
When my now ex husband left me (alcoholic, affairs), I was terrified. I always earned a lot, lot less than him, and not really enough to survive. I was pretty much totally reliant on him financially. 
Don't get me wrong, the first 6 months were hard, for all sorts of reasons as well as financial. 
But slowly I got to a point where I was able to raise my head high, raise it above the parapet, and I was able to start planning a future for myself financially. 
I'm still working on it, 4 years on. But it's been unbelievably rewarding. And it works. 
You'll get there. Slowly but surely, one step in front of the other. And you'll be super proud of yourself for doing that xx
