I’m in trouble

I just took out a MCA for 35k 2 weeks ago with a company that has helped me in the past but my business just got devastating news about our summer programs - our rent has tripled and as a result our summer programs won’t happen now my cash flow is a bout to die- FAST…. It’s the last thing in the world I want to do is to default on these guys… but I’m about to go out of business if I don’t think of a way to fix this - help!!!
