DS's Dad, my ex partner, says today - after long term health problems that his heart is failing. 
I just feel really panicky and I'm not sure I can put my finger on why exactly but, I'm very worried.
Already, DS did not get picked up by his Dad after school and he was not happy, tearful, very upset even when I was suggesting going to the park and buying an ice cream. The after school club leader had to help me calm him down. I think that was partly due to the hot weather and largly due to his routine being upset.
He always, daily, gets upset or at least asks when he is going to see his Daddy and the good thing is that I have always been able to say 'on Thursday and Friday night'.
I was extremely grumpy after DS was so moody with me today that we had to abandon food shopping and missed a couple of buses. I was especially pissed off as I was meant to be out with friends and had to cancel it.
I wish I knew what was coming next. Ex partner does not want to talk but he says he let himself out of hospital so is not being very smart as is obviously upset. I have told him I will pick up DS tomorrow also as he needs some time, but he has just said he will let me know...
DS knows Daddy goes to the hospital 'for blood tests' and he knows I have been to the hospital for a blood test too... I don't think think he knows his Daddy is really ill.
Just need some advice as have no-one to talk to about this really. Also I have been brought up in a totally non religious household and never had to deal with family deaths really, except more recently a very old great grandmother. I feel like I have no idea what to do or say, if indeed anything of course.
I am hoping for the best, but also feel a bit wobbly because I've just been told this and I always worry about the future especially for DS.
