I've been in your shoes and will suggest something different than the consensus here.

Instead of sitting around learning (taking online classes) actually DO something.

  - Create something with your own hands that gives you satisfaction.

  - Write a journal everyday to give yourself a sense of accomplishment.

  - Use those new EE skills to make a circuit that performs some small task to automate your daily life.

Sitting around and learning without applying the knowledge is a drain of your precious time.

Create, don't consume.
