i don’t know if i have clinical depression or not but i do have both adhd and anxiety and have had several phases in the past year where i have gone through long “funks” with depression symptoms a hell of a lot happened in the past year for me on top of the pandemic and being home alone most of the time so its probably due to that and dude i’ve had this situation you described happen over and over again to the point where it took me until 34 of the way through my fall semester last year to start pulling myself out a little at a time and even now occasionally i’ll slip into a state like that and it feels like utter shit you’re not alone my dude it really sucks and i’m glad i only have to deal with that occasionally and not all the time  sometimes anxiety will do something similar where i dread an upcoming event or something i need to do so much that i cant make myself do anything but doomscroll desperately looking for stimulus or motivation and then getting really panicked and mad at myself when i lose track of time and still haven’t started the thing one time that shit caused me three panic attacks in like 2 weeks and this is after i spent years getting help and medication for my anxiety to the point where panic attacks are usually rare these days
