<human>: Edit: Title should say Is not I'd. Oopsie-daisy.

We've been together since 2010, things started to fizzle out in late 2013 when she got major depression. Counseling is an option she has only recently started actively involving herself in, we haven't had sex in 10 months since she no longer loves me or is really stable enough to love anyone, my job is awesome and I make good money for a 23 year old woman ($76k salary) but at this point the relationship is hurting me so much.

She wasn't able to find steady work due to the depression and is negative money every month so I am funneling her about $300 a month. I don't care about that because I have so much excess money. But she only has about $300 in her bank account and alternates between sleeping and crying for most of the day or being wracked with anxiety over whether or not she is going to be homeless.

I am heavily into BDSM and this was my submissive and above all my best friend. I feel a tremendous amount of responsibility for her and she has no living family. I am honestly very concerned about something awful happening to her and I feel like if I cut her loose at her lowest and she failed I would never forgive myself.

Not being intimate with anyone is killing me though and I don't have it in me to play psychologist.

I'm really just exhausted, and have no idea what to do regarding this girl.

Can you summarize the given text in a few sentences?
<bot>: Partner is depressed,  draining me but is honestly mentally helpless at this point and I care deeply about her recovering. Not sure what to do?
