would you accept it if your partner was taking benzo-type medication, like xanax?

Depends on if the good outways the bad and his character as a whole. He needs to take meds, fine....but is he a moocher, does he have anything going for himself, does he have goals? He has to pick a struggle. Otherwise there's someone else who will check the boxes.

would their personality really matter that much to you, if they looked like a model?

No. I only cared about that in highschool.
It takes more than personality and looking like a model to build a happy, content, HEALTHY life with someone. "Looks fade" is a real thing.
As you get older you desire more.
Would you be content with someone who only has personality and looks that will fade?

As someone who is unwell and in hospital, I have taken benzodiazepines for years, probably not great but at the moment I’m on one of the least addictive types (I think?) regularly (3x a day) and a more addictive type as PRN and it’s regularly reviewed. I’m on other mental health medication and the hope is one day I’ll come off the benzodiazepines or at least only need them as PRN. If they’re properly prescribed and monitored and reviewed regularly, I know people who have found them life changing for the time they’ve needed them and, in my case, they’ve kept me relatively stable (I mean for a psychiatric inpatient), but not as helpful as I’ve found a mood stabiliser (lithium), but I understand people misuse them which is different. Sorry this was a bit of a ramble!

No. Benzos are a sticking plaster and not a solution. I would want my partner to take responsibility for their mental health - appreciate this can be hard but I have issues of my own and I would not want to be in a relationship with someone who is not willing to help themselves because I am not in a position to provide mental health support.

If someone is giving you crap for needing them for a mental health reason and you’ve been properly prescribed them, that is not acceptable in my opinion as they can be beneficial, you just have to be really careful. They should be more supportive.
