My pdoc is very firm about boundaries, most NHS drs are, mine deals with a particularly volatile bunch though.
Once we settled in once a week was plenty for me personally, but then I only turn up because I 'have' to otherwise I probably wouldn't make that.
Give it a chance, sometimes appointments just means you fill the time with more minor stresses than focusing on the things you really need to.

However if your on the standard 12 week block that is usually provided you will really need to focus on just what you want out of it.

All the best.
