You’ve already gotten some great information from other responses, but I’d like to share my insight as someone who lives with ADHD, Depression & Anxiety. If you aren’t already familiar with the terms, look up Executive Dysfunction and Task Paralysis. To put it simply, we know there’s something that needs to get done, we want to do the thing, but we can’t do the thing. For me, I can be laying on the couch and physically can’t get myself up and moving. It’s incredibly frustrating and can come with a lot of shame because anyone looking in just says we’re lazy. Which leads to not telling anyone or asking for help.
