my mom doesn't understand depression

i've been diagnosed and medicated for a decade (well on and off meds)and she still doesn't REALLY get it
  1. mom: you seem down today!!!!! stop
  2. me: i'm depressed today
  3. mom: why? today wasn't all bad.
  4. me: depression
  5. mom: but you're taking meds again shouldn't they work better than this?
  6. me: we're having this conversation, so they're working.
  7. mom:
  8. me: sorry.
  9. every time i feel depressed i feel like i fail her personally
