Failed and burnt out

I am a 53 man who has spent the last 10 years struggling in my role as in marketing operations. I’ve been promoted up over the years and I am now working in a role above my mental capacity. I simply can’t keep up. I’ve struggled for years due to my lack of true technical skill, but have managed to hold jobs by just working as hard as I can and trying to do anything that gets thrown at me.

The culture where I work is very hard. The pace is crazy. There are smart, fast and proficient people. They always have the answers. I can’t even keep up with what people are even saying.

I don’t want to work in this field anymore. I’m not built for it and trying to force it has left me pretty broken. Im depressed and suffer from anxiety so that I can’t even enjoy my time off. I don’t know where to go from here. I don’t need to make the money I make now, but I do need to provide quality of life for myself and my wife.

Where can I go from here? I’m looking for ideas for a change where I can make a living but not lose myself to it. Idk.
