ADHD time blindness and friendships, how do you deal with it?

I'm diagnosed with ADHD and time blindness really affects how I keep in touch with people. I don’t mean to ghost anyone but time passes without me noticing and replying later starts to feel heavy. sometimes I feel it’s too late to reply because of rejection sensitivity that makes me avoid messaging back even more. I also tend to run late to meet friends even though I care a lot about respecting their time. I badly wanna change that and take accountability. I struggle a lot talking to people too, there were times my mind just goes all blank like I'm not even mentally here that makes it even harder to be engaging. I’m curious how others experience this. What does time blindness look like in your social life, and how do you navigate or deal with it?
