I'm a graduate student taking all of my classes online. Initially all of the conditions that were conducive to my concentration were seemingly in place. Despite a somewhat noisy housemate, I had a fan to drown out a good amount of the noise. My laptop has also made a loud ticking noise since the day I got it, and the fan was able to drown out that noise for the most part as well. Now that the fan has died I'm not able to concentrate on my work, and since I was accustomed to the noise it made, I can't focus with any other fan, and I can't sleep either. This sounds odd to any person without concentration issues, I'm sure. What can I do to get back on track? I'm positive that doctors will only prescribe me anxiety/depression medication. I don't know if that will help.
