As much as it takes a ton of discipline, perhaps you can take a facebook holiday. The reason I say this is that I have a similar difficulty. When I'm taking a medication, any medication, I visit websites and reviews for that particular medication. Well, not surprisingly, I would contract all of the negative side-effects. I know that I need medication. So when I recently was prescribed Viibryd for this misery known as depression, I had the MD take the side-effects info out of the pack, and vowed not to look up any of the reviews. I have not been 100% faithful to no looking up any reviews, but I'm not obsessing on it either. And, again not surprisingly, this medication appears to be starting to work.

Oh, I also agree about the hypersensitivity that this depression causes...

In addition to your other coping methods, maybe you can just venture outside into nature and appreciate it.

Best wishes to you.
