Resistance and self doubt

I am swimming in a negative loop of resistance and self doubt. The topic is always resistance in working on my business. I waste my days reading how to overcome this ( funny huh) and feel terrible and paralized. At first I tried not to think about it too much with the hope of not focusing on this negative moment. But now I feel this full force and truly dont know how all this advice can apply to me, I understand it theoretically but in the moment I doobt anything can really shift my mood enough to create the drive and motivation I need. I am so afraid all of this will be for nothing and my dream of having a sustainable coaching business will crumble. It makes me feel defeated .
