Feeling low

Just feel low today.

Am about to start a training course, and I don't feel ready for it in any way, shape or form. Very nervous, and wondering what I've let myself in for.

My brain feels older and less capable of learning and retaining information, and this course is all about that.

I hope I don't fail. Not sure of the way ahead.

Sometimes I still feel lost - I feel like I am playing a role and I find myself looking at myself and wondering who I am. Weird. It passes.
