Courses that are close to Universities have this. Some Universities even have their own courses. I’ve played the U Maryland course. URI has a Par 3 near it that has intramural leagues on it at a reduced rate. It is a decent par 3 course too.
Alas, I think San Jose is a pretty busy area and may not have these things available.
I am no scientist but IMHO yips are similar to a beginner skier going down a steeper slope than what their comfort level is. It is not a condition as much as it is a phenomenon. Combination of panic and indecision. I can't simply tell myself to not care as much as I care.
There is no 'mental solution'. You just have to find a comfort level by practicing the shit out of it. If you can make a full swing without hitching you can putt too.
