I've been where you are now. A little older than you and after 20 years of marriage.
They say it takes a year to get over a bereavement and 2 years to get over a divorce. You will be grieving your old life for a long time.
I made the mistake of getting involved with someone else too quickly (which also turned out to be abusive, but I accepted his poor behaviour rather than being alone).
I now have my own house, which I've had major works done on and it's the first house I've owned which is completely mine).
Now, rather than resenting the silence, I love it. I have friends and family coming to stay, but I'm equally happy when they leave my little sanctuary again. I can lock the door and decide who I want to let in.
It's definitely not easy. However, I look back on the days of my marriage where I was sat in a full house feeling completely on my own. That was worse.
I own a dog, who is my wing-man and we do everything together. I've found it quite surprising which vague acquaintances have come out of the woodwork since I've been on my own and become true friends (and also people I thought were true friends that haven't been able to understand).
I never want to live with another man again. That doesn't mean I don't want a significant, committed relationship, but I won't give up my independence, my home etc to combine living space with another person again.
I love the fact that my home is always clean and tidy and I'm not having to deal with other people's mess and clutter. I love the fact that I can do whatever I want to do. There have been days where I've barely managed to get out of bed. There have been days when I've thought about ending it all. On those days a very good friend has messaged and reminded me that I've still achieved stuff. I've still got out of bed, got showered and dressed, walked the dog etc. Baby steps.
One day you'll look at the future and it might not be the future you'd imagined, but it will look good. You'll get there, I promise.
