I need help with keyword research, any advice appreciated!

As per post really, i shall show what ive done so far and am very open to suggestions. I use (and have really only ever used) market samurai, as i heard and learned via the 30 day challenge, and i hear it has a good reputation so that is what i thought id use. My niche is anxiety, my domain is managinganxiety.co.uk - Not sure if it is that wise to post my niche and ideas here but to be honest even if someone saw this as a good niche and (probably very easily) took over me!, if i get decent advice here then it would be worth it, plus hopefully help people reading this- and so far ive had nothing less than fantastic advice!
Ok need advice as to where in going wrong - anxiety is a massive area and i think quite lucrative with the right site and audience. ranging from, well im sure throw most topics in front of it - exam anxiety, job anxiety, etc, so big area im thinking. Site is around 1 year old now, well domain is, but since getting a rocket up my ass/motivation from this forum in the last week, it may well be all over the place with different themes, making a few banners and graphics, chopping and changing etc.

I want to expand on the theme, find some low competition and decent level of traffic (obviously!). can anyone tell me what i am doing wrong here, as i am struggling to find terms, using market samurai?


I have added screenshots to show the results market samurai has shown - if this is not clear or good enough can someone suggest a better way to attach?

Market samurai searches without filters or with - ie - no more than x competing pages or a minimum of x searches per day. My settings are set to uk - as the site is .co.uk - something i may need to revise but even so i thought that with the field of anxiety there could easily be some heavily searched words?

When i started 30 day challenge some 3 years ago (i have since left it and refound a spark of interest, in case you are thinking '3 years bloody hell..!!') the minimum was 70 searches per day, and 30, 000 competing pages. ive watched their vids again recently and they have changed to 50 searches per day and 100,000 competing pages. ive shown a screenshot with the latter implemented - only one, and this is a 'broad' match. with a term so vast as anxiety i thought there would at least be a few to try and target?

Hope i can get some guidance here, and am i missing something as plain as the nose on my face?? going about it wrong?

Thanks for any help here!
