DESPERATE. Laid off after 7 years and my skills are way behind in today’s market. Please help.

I got my first job out of college as a Front End Developer. I worked at a very small company for the past 7 years, making internal employee apps. Mainly worked jQuery. Strongest in CSS. Not proficient in Angular or React. No experience with next, testing (we did it manually), monorepos. I was laid off 3 weeks ago and got a rude awakening realizing how outdated my former workplace was. My skills do not match up to current job postings. I had two interviews last week, secured through referral, and both told me my skills are too far behind. I’m panicking because I have a family I provide for, including two young kids. In my previous role I was making 90k…. Now I’m fearing I can’t even make half that. I need some advice on how to improve my marketability FAST. What’s the fast track to boosting my skills and making me employable again? Please, no snarky comments. I feel low enough as it is. I’m honestly depressed.
