<human>: Ok, I've been trying to nut this out myself and with the help of other people, but I think I need some impartial advice (I wouldn't not say yes to bacon, either). The details are guaranteed to be exactly correct*.

I've started an mail order shoe shop with a friend who has anxiety. It's her first really big thing since she's had serious generalized anxiety (a few years back before I knew her). It's had problems since the start, but the business has managed to fund some stuff I was planning for a while, but her anxiety ups and downs make it really difficult at times and I'm starting to regret the whole thing but I'm reliant on the business in some form for a stable income.

The major problem is that just after we started the shop, she confessed that she had a thing for me. I told her I wasn't interested and it seemed to go away. It's come to light more recently that her thing for me has become a bit of an obsession: she tells our mutual friends that she's jealous of them and everybody else I know for being friends before I was. I notice she's also trying to draw me away from people I know, and gets angry when I'm interacting with others too much.

She's planning a holiday in a few weeks which means she'll be in the same county, and has decided to stay with me for what was originally a few days but has gradually become a couple weeks. Between being worried about her anxiety's reaction to things I've gone along with it this far, but now that I'm aware of her jealousy and posessiveness I'm honestly a bit scared to have her in my house. I have no idea how to bring this up with her without her anxiety kicking into overdrive, and whether her reaction could make her a danger to herself.

I think this business is going to fail, but I'd also rather not take all our clients down with us.

So, Reddit, do you have any ideas? Even better, anybody who has/did have anxiety with some insights? I'm fresh out and panicking...

<bot>: my anxious friend/business partner has a thing for me which has tipped over into obsession and I don't know how to deal with it. Any suggestions?
