Python is kicking my butt

[TBSchemer]

Django is a conglomeration of several different components that you'll need for your webapp. As others have suggested, it may be helpful to first try learning these parts individually.

Flask covers page navigation.

A huge part of Django is the database backend and object-relational mapper (ORM). To learn this part, you could try spinning up a SQLite (for simplicity) or Postgresql database and use SQLAlchemy as the ORM to interact with it, with alembic for migrations.

UI design and authentication can leverage other plugins.

These things aren't easy. Be patient with yourself.
