If I am completely honest with you CBP was quite lenient with you till you tried to enter the last time. Now in your original post the section you mentioned, they cited was for immigrant intent. Now by law they should have placed a ban on you. Did they mention anything about a ban? did they cite anything else in paperwork they gave you in the withdrawal of application? If you have ban then you have to wait for that ban to end. But if they did not place a ban (which is highly unlikely), then you just have to spend sometime in Canada and establish ties here. So the next time you try visit the US you can show, you have no intent to immigrate.
 
Finally if you are allowed visit in the future DO NOT overstay. As a general rule you can be there for 6 months, unless mentioned by the officer (like in the instance where they only permitted you stay only for a month). Violating it could have consequence on your future travels.  

I was on a student visa in the US for 5yrs.
 
Then overstayed for 4yrs taking care of my then “mother-in-law”. 
 
Came back to Canada in 2016 for 2 weeks. 
 
Then went back to US - they gave me a limited 1 month stay - I stayed 2 months. 
 
Came me back to Canada for 1 month. 
 
Went back to US January 2017 without getting interrogated nothing. 
 
Came me back to Canada December 2017. 
 
Tried to go back January 2018 & was denied. 
 
In Canada I live with my parents. Besides my drivers license & health insurance; nothing is in my name. 
 
Also, I only had a “one-way” since I wasn’t sure of my exact plans in the US.

If by “advice and concrete help” you mean for people to tell you how to get another visa, it’s probably not going to happen unless you can significantly change your home circumstances (stable job, own property etc).

My advice would be to give it 5 years, 10 would be better, get a good job, family, property etc and try again.

Another piece of advice would be to not do any of the above on another NIV.
