But wait…is that cos I’ve been lay down on the sofa all day browsing Lemmy? Come to think of it does that explain everything? Is browsing Lemmy 12hrs per day the cause or a symptom of something?

Funny enough, it could be a symptom of ADHD, depression, or some kind of compulsion depending on why you do it. For ADHD it could be the stimulation or avoidance of something else. For depression it could be seeking some kind of connection.

But only a medical professional would know enough to narrow down the possibilities to reach a diagnosis. And you might even get the wrong one first! I was diagnosed with something else before ADHD, and it was mostly the horrible reaction to drugs for the first that excluded it and led to the one that worked. It is slow and honestly I hope you find something that helps you.
