Hi, I believe that many of us are suffering (among other things) from a form of PTSD. What our partners did was usually out of the blue and deeply traumatizing to us. We then have to carry the family - if they are young we have most of the work, if older, our MLC partners often stop most if not all financial aid
Of course you are exhausted. Your xh has a moral and legal obligation to support his family and your contribution as the primary care give. Do not feel bad about needing this.
The good news is that it gets better - honestly. Your children are growing up, and are able to help more. their own distress moves forward (although I know few people who ever get over being abandoned by a parent. The scars are long and lasting, and abandonment is far more serious than most people realise)
Part of the internal journey is to learn how to take time for yourself while being there for your kids. It is a great thing to learn - it has helped me through hospital stays and other difficult situations.
What you are going through is just awful but you will survive
