Staying Focused?

So I've been going through some house drama. My bathroom essentially fell apart while I was in Amsterdam and since then I've had it ripped apart, my house filled with potentially hazardous dust, and have not been able to stay there. FOR THE LAST MONTH. It is extremely frustrating. Especially since where I've been staying doesn't have wi-fi and my macbook won't connect to the modem using the wire. Which means I have to go to my house, and attempt to accomplish things online while workers are stomping through my house, making all kinds of noise and I'm choking on dust. It is... not fun.

Top it off with the fact that I had a pretty important deadline looming, and my nights were filled with anxiety dreams of floods and toxic mold. It's been difficult, and I know my writing has suffered from it. I've been trying all kinds of things to help me focus, such as focus brainwave audio, which is basically the sound of waves crashing on the shore while underneath it tones that stimulates gamma or alpha waves play. I have to say that I was surprised that they sort of seemed to work. I don't know if it was just the fact that it was white noise, or if the brainwave thing was actually happening, but I did find myself able to focus more despite what was going on around me.

What kinds of things do you do to stay focused? I am sort of desperate for more tips. I tried the library, but they don't really have any "quiet" spaces there (plus they're doing construction, hello!) and I'm not so good in coffee shops where there's so much going on. Is there anything special that works for you?
