She said  “ I’ve been in this conservatorship for  3 years “ girl it was 8 years at the time 

  this came up in the past. Fans have wondered if she was referring to last court hearing or something like that 

I am not saying Britney should be in a conservatorship BUT this isn’t the first time shes be called out for lacking awareness (time and surroundings)  In the past we excused and said Oh Britney is tired from touring and jet setting. 

If anything it proves they’re abusing their power in the CONservatorship. Why would you force someone to work that lacks a sense of time or of their surroundings?

I believe she said "for a few years". At least I hope so

There's always a possibility, that the user, who told about it, might have misheard her. Plus he admitted that English is not his first language so it was hard for him to remember everything.
