Hey @MrVex
Thank you for reaching out and sharing what you are walking through right now. Finding out that you have BPD can feel like a lot to take in, especially when you are already navigating the world through the lens of ADHD and Autism. It is so valid to feel "wired" and emotional right now; your brain is processing a lot of new information while trying to manage a very sensitive nervous system.
When you're feeling all over the place, sometimes the best thing is to focus on small, manageable "anchor" points. I wanted to share some suggestions to help you navigate the journey ahead.
Since you mentioned being wired and not sleeping, consider how your Autism and ADHD might be interacting with your current stress. Reducing sensory "noise" (using dim lights, noise-cancelling headphones, or even weighted blankets) can sometimes help lower the baseline "volume" of intense BPD emotions.
When you are feeling emotional and scattered, try not to solve the whole diagnosis all at once. Just focus on getting through the next hour. What is one thing that makes you feel 1% safer or calmer? (it could be having a cold glass of water with ice, a specific song/playlist, or just stepping outside in your backyard just for a moment.)
I want to remind you that a diagnosis isn't exactly a definition of who you are entirely (although, as an AuDHDer myself, my diagnosis does make up a portion of my identity, but not all of it, of course), but it does give us a map to help us find the right tools. Many people find that once they have the right names for what they are feeling/experiencing, they can eventually access therapies like DBT, which are specifically designed to help with that "wired" feeling, etc.
If you haven't already, it might be worth mentioning your lack of sleep to your GP or a specialist. Since ADHD and BPD can both affect sleep cycles, professional guidance can help you find a way to rest so your mind can recover.
Please know that you are not alone in this journey. There are many people here who understand the complexity of navigating Autism and ADHD alongside BPD. We are all here to listen whenever you need to vent or share a small/big win.
