Friendly reminder that if person with ADHD doesn't reply to your messages for a while or forgets about important events because of hyperfixating, it doesn't mean that they don't care or that they're lazy or that they're upset at you or anything of the sort. When we get hyperfixated on something we can spend hours focused exclusively on that one thing entirely losing track of time, sometimes even forgetting about basic bodily needs. It can very much be unhealthy and is often a much bigger problem for us than it is for you. Please be understanding.
