I have discouraged/quiet BPD. I wouldn't wish it upon my worst enemy.
I've attempted suicide 20-30 times, most of them genuine but some genuinely just for attention. I have lost practically everything that has mattered to me. The majority of my friends left, I dropped out of school when I was fifteen, etc. But, I don't care. Not really. I've been put on so much medication that I constantly feel numb, and indifferent to everything. I mostly spend my time trying to cope with said boredom, usually just numbing my mind by playing video games for hours at a time. I can't even get a job, or perhaps go back into education due to severe and continuous psychotic episodes. It's hard to want to make changes in your life when you think that you're trapped within a simulation, deal with never-ending anhedonia and have a one-sided codependent relationship with your ex boyfriend of two years (whom you haven't even properly spoken to since the breakup).
I think that the codependecy, or "favourite people" aspect of BPD is easily the worst part. I am completely and utterly obsessed with someone that wants absolutely nothing to do with me. I've lost count of the amount of times I've had people close me describe me as creepy, weird, insane and other similar insults. I'm well aware of how irrational and odd my behaviour is, yet knowing that does nothing to change it. My rational mind knows that harassing my ex boyfriend through alternate accounts will drive him even further away, yet I continue to do so as in hopes I'll get some kind of reaction. Yet, I simply lack the ability to see that it's wrong. I have people tell me it's wrong, creepy, etc. but in my mind, it's the same as him doing whatever he can do to get away from me (even going as far as forbidding his friends from interacting with me, never mind just talking to me). In my mind, I see it as others saying that it's completely okay for him to make me miserable for his own sake, but when I do it I'm a terrible person. Him breaking up with me mere hours after my suicide attempt was fine, and I'm the one to blame for having a full blown breakdown during a time of need. Perhaps this is due to my lack of empathy caused by my autism, but even so, I have absolutely nothing left while he has everything going for him (university student, high income job, etc.) and therefore believe I'm allowed to be at least a little bit spiteful.
Due to BPD being almost exclusively a trauma disorder, only we can truly sympathise with each other. But, even so, you will never be able to fully relate to another person. It truly is a lonely disorder. My abandonment issues came about as a result of my mother's suicide before I had the chance to turn five. My hypersexuality that started around the age of nine, is a result of multiple instances of sexual abuse from different people throughout my childhood. My rapid mood swings can be accounted to my father, who would regularly berate me and cause me severe distress whenever I did something he even slightly didn't like (one specific example comes to mind, when eight year old me said I wasn't going to bring a bag to my school dance which resulted in him kicking it around the room, then throwing it straight at me while screaming and swearing). But, my trauma is mine. I'll never meet someone that went through the exact same things I did, and therefore will never meet someone able to fully comprehend what I am going through.
I look forward to the day I finally go through with ending my life. It's the only way I'll be freed from this miserable way of living.
Sorry this is so long, I have a bad habit of rambling and repeating myself lol
