Struggling

I'm always in this constant battle of doing more and getting so overwhelmed that I just can't focus on one thing. I'm so confused at times about what I should do. If I could just sit down and not get any other thing to drive my focus away but it's impossible because I have to do a lot to keep things in order. And then I fight off this exhaustion by distracting myself with trivial things under the guise that I deserve it so I won't too overwhelmed but does it really? I'm in this constant battle now. I don't know how to win,.
