Here’s the problem with self diagnosing and using the internet to research… you’ll end up convincing yourself of all sorts of disorders. Trust me, I’ve been there and gone that. You’ll go from “causes of hangnails” and hours later you’re convinced it’s due to a tumor. Leukemia, MS, Lupus, and a multitude of other “diseases” all have relatively the same symptoms, same for emotional issues. If you’re a God fearing person, talk to Him, He is our comforter, if you’re not, I highly recommend becoming one. He is Who created us. Who better than to treat us than our Creator? Most things from a psychological standpoint are related to matters of the heart, past hurts, etc., but once you realize that there is a God and that He loves you so much that He sent His Son to die for you and you accept that and lean on Him, everything in this life seems of such little importance. I’ll be praying for you, I hope you feel His presence and receive the peace He has for you.

Definitely never self diagnose and always worth bringing it up to your psychiatrist for further analysis - bringing up stuff like this helped me understand dissociative disorders better.

Yes definitely ask your doctor. I’d even recommend you try finding an online assessment just to see if the symptoms you’re having align that way and you can take notes on that as part of what you’d like to discuss with them. Tell them the similarities you’re seeing and they’ll know whether or not you need an assessment or if it could be something else.

the thing about self-diagnosis is that it's literally not possible for some disorders, including cluster b personality disorder like BPD, because the hallmark characteristic is that there's nothing wrong with you, it's everyone else who's the problem. you are always the victim and anything bad that's said about you is exaggerated or made up. if you have any inkling that you may have a personality disorder, it's not a cluster b. a narcissist doesn't care about getting better because they don't think they need to be better, that's just how their brain chemistry works. if you look up symptoms and you see the little Google overview that says "requires a medical diagnosis" trust that and talk to you doctor
