Midlife crisis?

I’m in my early 40’s and feel like I’ve hit my midlife crisis! The anxiety over life, death, my kids, my relationship has increased significantly over the last 2 years. The things I used to love and enjoy doing are now in the back of my mind. I struggle with wanting to enjoy them again. Even had an affair with a friend that I know is too toxic for me. But I can’t stop obsessing over it. Please no judgment. We’re all human! You’re not perfect. I want to hear about anyone else’s midlife crisis if that’s what it truly is. Thanks
