Just read your thread op and wanted to send some
and hugs your way. You sound like you're really going through it at the moment. It feels so all consuming and horrible right now but it will start to slowly get easier as time goes by. Just keep doing all the little things (some great suggestions above) like going for walks, watching box sets...etc just to get you through each hour. Eventually the fog will start to clear and you'll be able to think more clearly and get angry which helps, trust me.
I'm going through a split after 13 years together. Currently in month 4 and definitely starting to feel a little better already. For 3 months I have felt confused, ready to beg him to come back, cried so very much, couldn't think straight about selling the house and the new life that lies ahead...etc the whole lot terrified me and made me want to curl up in a ball and just hide. However this past week it's like a veil has been lifted and I no longer feel as afraid of what the future holds. In fact I'm starting to slowly look forward to my new life by myself and even feel a tiny bit excited by it.
I'm creating a social life now, one that was non existent before. I have leaned on people for help with the emotional side and have found people only too willing to help and have made some friends in the process. My weekends are now starting to fill up with meals out..etc and my friends have become so precious to me right now. The social side has been a fantastic distraction from the misery of the split and has made me realise that there is a life out there - I just need to go and get it.
I know my situation isn't quite the same as yours as you've been together with your dh for such a long time and it must be such a wrench for you. But I just wanted to offer a little bit of hope that things will get better eventually, even if it doesn't feel like it right now. Just concentrate on getting through this initial blur and allow yourself the time you need to heal. As horrible as it feels you need to cry, wail, vent...etc because if you keep it in it will just take you longer to recover from. Remember you are still in the very early stages of the split and are suffering from shock right now so your emotions will be all over the place. Take care, keep eating little 'n' often and try and rest when you can. Keep posting if you're having a dark moment.
