Divorced men - how do you deal with living alone?

Recently divorced and struggling to understand this new life.

I've been spending a lot more time at work and my input has increased but I'm still looking for things to do outside work that will keep me busy. Trying to come up with a routine that will be productive as being a workaholic won't be sustainable in the future as I'm 33 so plenty of time to learn new hobbies/ skills etc.

What do you guys do if you live alone? Have you taken up new hobbies? Any new interests?
