How does one stay on track?? Like, how can someone stay focused for more than an hour at something?

OK, so I am terrible when it comes to remembering to do things. And even worse when it comes to doing them. I get easily distracted, have no clue why and it sucks. Like, I can do the task, but I’ll keep getting distracted by dumb things like my cats or like a pencil, dumb stuff like that. I do have a therapist, but she says she’s not sure if its ADD or just my depression. I don’t get to talk to her till next week, and it’s kinda effecting me right now, so if anyone know how to deal with getting distracted easily, I’m all ears.
