Lost my consulting gig after 7 years - completely lost right now

So I'm 35 and just got the boot from my environmental consulting position that I've been grinding at for 7 years. Everything was billable hours and the major contracts I was managing just lost their funding. Tried switching to different projects within the firm but nothing panned out

Had an interview lined up a few weeks back since I could see this coming from a mile away. Thought it was going to be perfect - exactly what I wanted to do. But I totally choked during the interview and got the rejection letter yesterday.

Between managing my rental properties and trying to keep my aquarium setups running I thought I had my life figured out but now I'm questioning everything. Anyone else been through something similar in this field? Could really use some perspective right now because I'm pretty much spiraling
