I do my reviews on top of having a retail job, so I have run into a lot of stress at times.
Somethings that I do so that I can try and get a hold of things are pretty easy for me.
I'll make time for myself, set it aside some how and just forget about everything else. It can be hard to make my brain shut off when I want to be working on reviews or other things. But it helps. Normally I will take a walk or soak in the tub. Maybe even just veg out with a movie.
