I want to preface this by saying I’m not trying to self diagnose or receive a diagnosis from the internet. Just sharing my experiences and wanted to see if anyone who has a PD could tell me if my experiences are potentially indicative of one. This is a long one so thanks for reading in advance. 
So over the last several months, maybe up to the last year, I’ve been experiencing some varying degrees of symptoms that I feel like might fit the premises for a PD diagnosis (or at least consideration) and that my current meds don’t always help. 
Here’s the background information. I’m a 19 y/o trans man, grew up in verbally and emotionally abusive household. Both parents have several mental illnesses. Mom has undiagnosed BPD and maternal grandmother had NPD. I have been diagnosed with ADHD, PTSD, Depression, severe anxiety, disordered eating (not an ED), and OCD tendencies. I’m currently taking Wellbutrin (been on for ~3 years), Strattera (~5+ years), and Effexor (~2.5 months). All of my current meds manage my anxiety, depression, and ADHD to the point that it minimally affects my day to day life and stability. I’m currently in therapy and have a psych, and have been in therapy nearly all my life. Now is the first time in my life I’m out of my parents’ house, fully being allowed to be independent and make my own choices, etc, (standard experiences after “adulting” out of an abusive, toxic home). Now, here’s what’s been going on the last few months. I attempted suicide for the first time in my (long, and very depressed, unstable) life back in February when I was on campus at school. It wasn’t a full on suicide attempt though. I remember thinking to myself, “I don’t want to die necessarily, but I don’t want to be alive either. Why don’t I just take a bunch of painkillers and flip a coin to see how bad it is and what happens when/if I wake up.” For all intents and purposes I was trying to hurt myself and wanted to jump off that bridge but I wasn’t trying to kill myself. In addition to this it was a fairly rapid decision and the first time in my life I’ve acted upon it. I’ve been far more suicidal and depressed as a kid than I was that day yet never actually tried to do it. And as of that day I was an adult, away from my horrible parents, at my dream school, and got to go home to my fiancé and pets that I love very much. All this to say I still decided to try to kms. (Wtf, right? That’s a little random). After this attempt I dropped out for the semester under the pretenses of a “medical withdrawal”. I went home, and got into a two week inpatient crisis program that did me lots of good and helped me get better and more stable. While there they had a psych I met with multiple times and spoke to about some of these PD concerns. She switched me off my lexapro (which had been severely contributing to my suicidality) to Effexor (which after only a few days made a huge difference). I then had some psycho education with my trauma therapist there, in which she explained hypomania and hyper mania as a PTSD manifestation. This was the first time I had learned about it and it explained nearly all the PD symptoms I was having. These sort of mini-manic episodes, impulsivity, rapid mood changes, volatile irritability and anger, going from feeling completely fine and stable and okay to suicidal seemingly at the drop of a hat. So I tossed it up to that. 
Flash forward to now and I still have a lot of these symptoms even though my PTSD healing and therapy work has come a LONG way. I’m much better than I was then and have done a fuck ton of healing and processing to get here. My ptsd is largely managed and has calmed down now. Because of this, I’ve been wondering again if maybe there’s something undiagnosed going on as I’m genetically and environmentally predisposed to it. I can go from having a good day and feeling happy to wanting to literally hurt or harm myself seemingly out of nowhere- not even necessarily in a reaction to something that happens to me. Though it often does happen after experiencing an inconvenience (ex. I get a bad grade, BOOM I literally contemplate suicide). I experience rapid and unprovoked mood and behavior changes especially irritability or frustration. (ie depressed to manic or vice versa). I experience random intrusive thoughts about a variety of things- self image, suicide, my relationships or experiences, etc. my parents told me growing up that I was delusional as I frequently misremembered experiences or conversations (now I’ve chucked this up to gaslighting and actively being traumatized by them). I’m impulsive and act on things without much forethought often leading to risky behaviors (ie attempting suicide, excessive drinking, smoking/getting addicted to weed, sabotaging my success and relationships when things are otherwise going well.) I dissociate like there’s no tomorrow. I regularly feel like my reality isn’t “real” and things aren’t REALLY happening to me or being experienced for real. I get paranoid when I’m stressed about something. That something is going to go terribly wrong somehow or result in severe consequences when it’s not rational. I regularly feel empty, sad, and lonely (depression?) even though I have a wide support system and a spouse that loves and understands me. 
If anyone with a PD or knowledge of PDs could share any advice, information, or related experiences I’d appreciate it. TIA
