Listening, understanding and aphasia

I can hear, but:
- I have difficulty listening, and understanding what other people say
- I have difficulty understanding some words
- I have difficulty following conversations.
I can mostly understand what others say, but this gets difficult:
- in a crowded or noisy place
- when I'm tired or anxious
- if the other person talks too quickly
- or doesn't make it clear what the topic of conversation is
- or uses complicated words or long sentences.
