I'm very sorry for your loss. My H died after a sudden illness last summer. It was totally unexpected and FAST so damn fast.*
We'd been together for over 30 years. While I'm working, getting necessary things done, appear to be okay I am not okay. I miss him so much. We're both independent personalities but after that many years we were also deeply a couple. He was due to retire next year and I'm angry he didn't get to relax and enjoy that part of life.
I miss his companionship, our total knowledge of each other. Nobody will ever know me as well as he did. We never had children so I feel alone now.
It's hard 💗 but you have to keep going. He wouldn't want your life to stop now would he? The pain doesn't go away but it subsides over time. My advise is to live as he would want you to. Don't let his absence be your ending too. You'll never forget him but I'm confident he'd want you to go on now.
Take care of yourself, allow yourself as long as it takes to recover. Maybe you never fully recover. Life will be forever different now but it's still worth living.Try to surround yourself with people who are kind and good as much as possible.
*I've thought a lot about this since H died. A sudden death is shocking, it's hard to believe it happened. But usually it means the person didn't suffer a long time. A slow death you get time to say good bye but the person usually does suffer pain. I've decided death generally sucks and I hate both versions.
