I still feel like this. I just start small with attainable goals.

I write down what I want to accomplish and make it something I can easily see. I have to be able to do it in some reasonable time too. Could be as simple as calling the pharmacy for a refill.

Then I do it and write about how I feel about the results. Over time I look back at the results and see how I felt. It's good to see progress.

I just kept on doing this and I was able to gradually do bigger things that took longer to do. I don't write as often now but I remind myself that I'm reaching goals and getting things done.
