How to keep going?

I was recently laid off. While this is normal in my industry atm, it really hurt and has left me in a very vulnerable place. I had covid, very very badly in 2020. I was in the news many times and I almost died a couple of times. Work was great while I was on disability and I even told the press as a help to the company how great they were. I returned to work, with a physical disability. I worked very very hard to return in the first place and be able to walk in general to be ready for a big work event. We had the event and I was great, my superiors were happy, and we were buying a home since my job was safe as remote. A month and a half later the layoffs happened and I was chosen despite not being related to the others who were let go, I worked for a different product than the one they were reducing. It made no sense. I try to stay positive, applying for remote and in person, interviewing, and using my mentors for guidance on types of jobs, resume review, and cover letters where applicable. I have gotten to the me and the one other person running 3 times now, all to end up losing out. The last one, the "culture fit" interview was in person and all just nerding out for vibe. That part went amazing until I stood up and the others who came in after I was seated saw my cane. Their faces changed, and I instantly knew I was going to lose out, which the feedback was I was "Perfect" but the other person just fit in better. Another one it was very obvious they weren't comfortable with a woman leader. I need work, I have vast experience on a corporate level and all I get is "overqualified" or "underqualified" or you are great but we went with this other person. Its exhausting, its heartbreaking. How do I keep putting myself out there only to fall short. What else will Covid have taken from me if it comes down to this? Im an overweight woman with a disability, but thats not all I am. Im a capable professional with a lot of skills. Why is the former always what people focus on more?
