Prioritize. There's nothing you can do about the screws now. Worry about that later, when your immediate living environment is no longer overwhelming. Worry about that after you've fixed what you CAN fix. If all else, you likely have a security deposit on your apartment. That will pay for the repairs.
When you think about what is upsetting you, what is the first picture that pops into your mind? The picture of a table in disarray? Or is it a smell? The smell of dishes left for a week? The feeling of tripping over something? Whatever that thing is, that's likely what's bothering you the most about the mess in your home. Whatever that first thing is, that thing is first priority. So, clean the table/rinse out the smelly dishes so they don't smell anymore/pick up what you've been tripping over. Now, you're in "cleaning mode." Say, you just rinsed out smelly dishes. Now, what do you see? A pile of rinsed dishes that could be washed? Do that. Now that those are gone, what do you see? A dirty counter? Wipe it with the dish sponge. Now that that's clean, what do you see? A wall that could be wiped down? Use the dish sponge for that, too. Use the ability to focus on little things to your advantage, to take cleaning in little bites like this, beginning with whatever is causing you the most distress in your environment.
This works for me, because I find that the "big picture" of a situation (like a trashed apartment--I've been there!) can be way too overwhelming. But, one task? Yeah, I can do that. And, when that's done, I can usually segue from that into another, nearby task. It's the difference between going, "Ahh, I have to pick a bushel of berries. There is a massive field of berries in front of me; where on earth do I start?!" and going, "Oh, look in front of me. One berry. I think I'll pick it up. Oooh, look, right behind that berry on the path, another berry! I'll pick that one up, too!" as you slowly follow the trail of berries down the path to where you want to go, you'll eventually have the same bushel of berries. I hope that made sense; I'm not always great at explaining things like this.
