Uh, yeah, he obviously doesn't see how serious your situation is. Do you have anyone else who can hang onto your pills for you? I mean, how often do you take them? If it's once a day and you know someone else nearby, that might be an option.
This guy doesn't get it. If he did, he'd have them hidden or locked up somewhere. And "watch yourself?" That's just cruel. You ask for help and he doesn't give a ****.
Don't feel bad for needing help. He's just insensitive. Some people are very solipsistic...as if nothing involving other people is their problem unless it involves them having to get up for another beer for themselves...then other people suddenly matter.
You might need to temporarily stay with another friend or family member to get the support you need in this critical time.

You're not alone.

Here for you.
