Good read. It is hard, I'm in the process myself and pushing to complete asap. I found the physical aspect of flying very enjoyable and satisfying though. If you can find the reason you started this journey you will be motivated to continue. I found that looking out the window once every time and just absorbing the view, where you were and what you were doing really helped.
I myself am struggling along with the theory, maybe ground school wouldn't be a bad idea to give myself some structure.
Good luck and keep at it.
