I don't know what to do anymore

As the title says. I didn't know what to do anymore in my household. I was diagnosed with ADHD when I was 8yrs old and I'm now 40. I'm currently on Adderall XR and some days I feel like it works then alot of times I feel like it doesn't do shit.

I'm starting to feel like I can't get anything done anymore. I dread coming home to do the usual tasks that need done for the day as my girlfriend (Non-ADHD) is pretty much a clean freak and if I miss something I'm told, I need to Pay Attention more. Or I'm treated as if I'm child being yelled at for fucking something else up.

I'm so tired of getting yelled at. So tired. I'm to the point where I just want to disappear from everything and everyone. I know I'm not the only one that feels like this. I just needed to vent somewhere because I can't talk to my girlfriend about ADHD. She just doesn't understand. Who knows this post will probably get deleted like the last time I tried to get some advice here.
