Hello, thank you for sharing your story with us,
I too have been through a similar situation 10years ago in Sweden, I used to smoke weed and my ex girlfriend wanted revenge for me leaving her so she told the CPS that I smoked weed, I had to do six months of tests to be able to see my child, of course I cleared the tests and they could not stop me from seeing my child.
I have again been through a similar situation, thus time the Swedish government threatened to take my children because we chose to homeschool them, I told my story and got a huge response. Since then I have started #familyprotection a support group for people who have had any dealings with the child protection services.
I think your story should be told and heard, if you were to write a post about your experience with your government i would make sure it gets noticed and hopefully you could get some much needed support and advice.
If you do write a post tag it with #familyprotection and it will get the attention it deserves.
Stay strong and never give up.
Bless.
