Broke, working for free, and feeling hopeless. Need help.

Got an MBA to after getting laid off. I was a Business Analyst at a bank and had been working on a startup before getting laid off. I wanted to skill up and learn as much about the startup world as I could. So I went to the Fulltime at a T30 MBA program. Everything was going well. I started working at the second largest VC firm in my city during grad school. It paid next to nothing but I was learning a ton and making awesome connections. I looked at it as an investment into myself so I kept pushing. I exceeded everyone's expectations for the role Then I got an opportunity to work at a fund everyone in the startup ecosystem has heard of so I moved across the country, despite even less pay. I did even better work for this firm because I learned from my precious experience I thought everything was going to work out. But this is where everything gets ugly. The firm I interned with in grad school and was in the midst of negotiating an offer with, shut down unexpectedly because the managing partner couldnt finalize his next nine figure fund ( Basically took his ball and went home). Ok, I can deal with that so I took a non-investment role (advisory and partnerships) with another VC firm where my pay checks are tied to the money I made for the firm. Unfortunately, my MD developed a massive drug habit and has done zero work (Cocaine and Ketamine almost daily). Any client I bring in, he screams at and tells them they are shit. So we cant keep a client and I have stopped bringing new people in to save my reputation. I am still doing everything I can for the few companies left because I want to stay true to my word. So officially, I have a job, but I'm making nothing. I've been interviewing for Product roles across the US and networking extensively but it's been months and I can't land anything. Everyone has the same feedback that I'm a great culture fit but they are going in a different direction. My bank account is zero and the only reason I am not currently living on the streets is because I have wonderfully supportive parents who are able to help financially and a finace who really is my rock. I am thankful everyday for those two things. I have an undergrad degrees in Engineering and economics in addition to the MBA. I thought all of that would make me hireable for a number of roles. But instead I feel like my financial future is ruined and all my studies and investments in myself have been a waste. I dont know what to change and I dont know how to get off this hamster wheel of interviews and rejections. Each cycle of interviews it becomes more and more difficult to hide everything I've just share and to show the happy, and grateful person I am. I'm taking a shot in the dark here, but Blind if you think you can help me, I could really use a hand.
