Laid off.

I’m a 36 year old woman that just got laid off along with 7 other coworkers. Our billing deparment is closing down due to the company getting a new EMR system that has AI integrated doing pretty much everything our department does. I was with that company for 9.5 yrs. I feel like I have to start from 0 again. I moved up within that company and took 5 different roles starting as a receptionist to becoming the executive director’s assistant and then moving through to the billing department. I don’t know how to feel, almost in a nonchalant type of way, I feel nervous thinking on having to do interviews again. My last day is tomorrow. I guess just some encouragement is what I’m looking for. I feel like I’m worthless right now. I feel lost.
