So, looking back on what I remember about anything before age 15, I can see bits and pieces of what would now be symptoms of BPD. But it didn't really start affecting me until about grade 7 ? And then it was a slow increase until about 18 and then took a HUUUUGE hit and got significantly worse almost over night. Like something that was holding it back broke under the pressure and out came unfiltered unbridled mental illness. 

But I was just wondering when everyone else started experiencing their symptoms getting to the " unmanageable without professional help " point ?
