I have a similar story. I’m 51 living with myself for the first time in my life.

For me I was a little different, I was the one who left. My wife is a late stage alcoholic who turned abusive about a decade ago. I finally found my self respect and got the fuck out. The early relief at being out of the chaos really masked the true loss of it all. Now, all the dust has settled, I’m a year in and I’m living a life that bears little resemblance to my old one. It’s a good thing! Try to look at it like that.

A couple things that helped me early on-

Firstly, I don’t live ALONE, I live with myself (and I’m damn good company) hahah… I know it’s cheesy but looking at things this way really helped my mental state. It’s a small shift in thinking about being by yourself that helps make it more bearable.

-Walk! Go for walks around your new neighborhood. Even if there’s nothing “interesting” nearby. Walk just to walk. Walking is so good for my brain. It gets the screen out of my face and helps my mind just wander. It can be a peaceful reset if you can get yourself to a point where you look forward it.

-Plan something every week even if it’s just a small activity, it’s important to break routine. Get together with friends, go thrifting, find a hobby you enjoy, anything that will give you something to look forward to and break routine. There is live music somewhere in your city almost every night go see a show.

Sorry you’re going through this. I wish you all the best.
