Punkatheart I really feel for you. Five years ago I was where you are; beside myself with rage and grief and pain and trying to support three dcs, the eldest aged 5.At the same time I also found out I had hep c and I went through the treatment for that for six months which was gruelling, completely unsupported by exdp. I remember sobbing my heart out in the bank because the cashier had smiled at me in a kindly manner
I used to feel murderous thoughts that really shocked me and my heart raged for myself and poor innocent dcs. I couldn't believe he wouldn't see them or pay maintenance for them. I couldn't afford to do things to our house which was falling down gently around me
Now I am very happy and have been for a good while
My advice, fwiw would be this
Be kind to yourself. I is very early days to have gone through such an enormous change and loss and you are bound to be feeling a maelstrom of emotions. That in itself is exhausting and draining so eat well, sleep as much as you can and try to have some exercise every day
Accept that is its perfectly normal and healthy and right to feel anger. As others have said, try to channel that energy into helping yourself . If it becomes too much for you,find ways to vent. I used to write vitriolic emaills to my exdp and, (in the main
)put them in my drafts box, put on really loud music and dance around my kitchen whilst pretending i was kicking him etc etc.
Take pleasure in small things - a cheap bunch of flowers, a new lipstick,feeding the ducks, coffee with friends, a hot chocolate with your dd, do a good turn for someone, anything that gives you a lift and doesn't cost you much money. Try no to worry too much about the house for now - I used to just put another poster over the damp - leave that for another day
Get legal advice - go with a friend with a list of questions for a free half hour's legal advice - lots of solicitors offer that. Try to open your post as it comes and keep on top of it. It won't go away if you ignore it.
Try to look forward in stages. Don' think too far ahead, just set yourself manageable goals, such as by christmas you would hope to be feeling a bit better and have a nice day with your daughter. If the future frightens you, focus on the here and now for the time being. After Christmas has gone, aim to keep going and keep strong until Easter. And so on
It is hard when a relationship breaks down and you will not feel better immediately, but keep going with your head held high and you WILL feel better before too long
