Hello and WELCOME to BPDR!!
It's doesn't matter if you are diagnosed with BPD or not to use this site as a way find your path towards happy, healthy living. The tools and the people on here can help. I would talk to your doc about it, but remember BPD is a really difficult diagnosis to make-- it looks like many other mental health issues and also can overlap with other disorders so it's important that the docs are the ones to diagnose. And remember, depression and anxiety can be pretty debilitating in and of themselves sometimes-- they certainly were for me (diagnosed with GAD, MDD and BPD but now I'm clear of all MH diagnosis).
Anyway, feel free to just jump in around here. We're happy to be getting to know you. Please ask if you have any questions, otherwise just post when and where you see fit. The tool section on your upper left has some really great ways of combating some of our issues-- they can really help. You can beat all of this, but it does take some time and real effort. We'll be here to help you along the way.
