I have never heard of someone being diagnosed with BPD after only being in therapy for a month. I wasnt diagnosed until 4 or 5 years after i started therapy. But, i do believe you.
That's the problem in my eyes though, this sub's followers aren't trying to understand BPD (many of them, anyways). I totally understand wanting to heal from abuse, but again, many of the people here are confusing BPD with NPD and are using their feelings as facts (at least what I've seen). I agree when you say i dont know what it's like to not have BPD, but i can only imagine that it's much less of a living hell. If this subreddit was simply for escaping abuse without tying BPD or any mental illness into it directly, i wouldnt have a problem at all as i myself am a victim of abuse and trauma. My problem with this sub is simply the fact it stigmatises BPD and it is so, so, so misleading and just plain hurtful.
The other angle is seeing the world from a pwBPD's point of view. The unpredictable and uncontrollable mood swings and splitting, the mental and physical exhaustion, and the constant frustration and suicidal ideation we deal with every couple of hours. The dissociation we sometimes get when we experience any intense mood, the crippling anxiety and paranoia of not wanting to die alone, the fact no one takes us seriously after multiple suicide attempts (because "if we truly wanted to die, we would've by now"). It's the frantic efforts to avoid abandonment and saying things we dont mean and acting impulsively, then feeling immediate and overwhelming guilt and regret. Can you imagine what it's like to have a noose around your neck or way too many pills in your stomach at 2am and then you wake up feeling totally fine (mentally) the next morning? It isn't fun. I have been there more times than I'd like to admit. BPD isn't all negative. There's intense passion and joy we feel when we love something or someone. The loyalty we have to our partners and the lengths we go to in order to protect them and make them happy. The ability to empathise with others easily and understand their emotions. BPD is not all bad and we are not all abusive or toxic like this sub suggests. Again, most of the stories I've read on here sound more like NPD abuse cases or even sociopathy, not BPD.
