Does how you feel effect progress?

I completed rTMS on Friday and thought I was seeing a tiny bit of improvement in my mood and energy. Thursday night I was feeling a bit dull and negative. Friday night after I finished I had a lot of frustration (just terrible traffic). Then, early Saturday morning my dog fell and couldn't get up. I was freaking out. It seems to be just bad arthritis; he is doing better now, but still not great. He's a 12 year old lab so I know this could become a quality of life thing if he isn't able to go for walks any more.

I'm feeling really worried and sad. I know that's normal for the situation, but it also makes it hard to know how I should feel. I don't feel better right now.

My question is, does your mood and attitude effect your progress during/ after rTMS? Should I be trying to stay positive, and push myself to try to make the improvements I hoped to see from treatment? Or does the fact that I still feel kind of low and lazy mean treatment didn't work?

The timing of things is just crummy. I'm confused and worried.
