Bored describes the person feeling it; boring describes the thing that causes the feeling. Mixing these up is one of the most common learner mistakes in English.
What you'll learn
Many English adjectives come in pairs built from the same verb: bore → bored / boring; interest → interested / interesting; excite → excited / exciting. The -ed form and the -ing form describe two completely different things.
The -ed adjective describes how a person feels — it's about the person experiencing something. 'I was bored' means I felt boredom.
The -ing adjective describes the thing, person or situation that causes that feeling in others. 'The lecture was boring' means the lecture caused boredom.
A simple test: if you can say 'it/he/she makes me feel ___', use the -ing form for the cause and the -ed form for your own feeling.
'I am boring' means you make other people feel bored — to say you feel bored yourself, use the -ed form.
The lecture is the cause of interest, not the one feeling interested — use the -ing form for a thing that causes a feeling.
You're describing your own state of confusion, so you need the -ed form — 'confusing' would describe the instructions themselves.
The feeling caused in you is always expressed with the -ed form, whatever caused it.
