I havent been officially diagnosed. I tried going to see a therapist, but he didnt care enough to do anything. He just said it's a single depression episode and mild ptsd despite going through this for years. Feel free to see other post about it.

Anyway.

On top of my mood swings being all wacko, I started noticing that I've been absentminded and quite forgetful. Worse than usual. 

For example, I would forget something in a room like my car keys. Go back to get it. End up grabbing the wrong car keys(I have multiple cars). They obviously dont  work. Get irritated, through a mini fit and go back to get the right ones. Give or take another try. 

It's not just with keys. Food too. Like dipping something in a sauce I absolutely hate, yet never done it before (besides tasting it to find out I hate it). Or literally anything. I'll be walking or driving, and just end up not noticing i passed my stop. Or things like that. Like my mind isnt there..is that normal? My research into BPD doesnt say much about this. And I'm pretty sure it's not related but I cant help but wonder...maybe its impulse? Idk. It just feels like I'm losing my mind or losing touch with the reality around me.
