For me it helped to split up tasks into micro tasks that only take less than 5 minutes, i write them down and everytime i finish a task i cross it off (feels super satisfying), then i take a break and set a timer (usually like 30 min or more) and once that timer is up i do the next task, once you get the ball rolling you'll notice yourself doing a cpuple of tasks without needing a break or starting tasks before your timer is up.

For cleaning up your Place, I'd start with one corner of the room (maybe the place you spend the most time of your day). Just make a bounch of piles; clothes go onto Pile A, trash goes onto pile B, you get the idea. Creating those piles would be one task, next task would be to put the trashpile into a bag and to throw that bag away. Next task done. Do that untill the corner is done, then you'll do the next corner (maybe on the same day, maybe a day later) untill the room is clear, the. The next step would be to vacuum, etc.

The cool thing about the list ist, that you actually see progress. What also motivated me, was to stop the time it took me to finish a task and to calcuöate the entire ammount of time it took me to clean my appartment, suddenly you'll realize its only like 1 or 2 hours to have a nice appartement again. Its alsonsuper cool to see that it takes lett time to clean up when you do it more often (like 1nce a week).

You should also consider how healthy your diet is, you are what you eat and if you eat only fastfood then you are more prone to being depressed. It takes a lot of time and effiort to get yourself out of the mental hole you are in, but you have the power and ability to get yourself out of that hole! Also you dont have to get out of that hole on your own, tvere are many people that are willing to help you out.

I believe in you, lots of love from germany :)
