So sorry you seem to have exhausted yourself with stress (both the useful and the red flag variety) but glad you are taking remedial action. It is exciting when starting a new venture and I'm wishing you success but, please remember - you are more important than your work!

I wish you recover fast!
As someone who doesn't know either Python or blockchain-related stuff, I'd love to know about what you learned in more detail and what seemed easy or hard.
Keep going!
