Decreased patient's since covid

I've been in practice since 2007, I use word of mouth and digital marketing for new patient acquisition. I do my best to use referral statements in my practice. My problem is I've seen my patients dwindle ever since covid. I have a new website and I do SEO but nothing seems to matter. I've gone in the community and started networking again, but haven't seen the fruits of my labor yet. I'm super depressed and dejected as my practice is evaporating in front of my eyes and my numbers are close to what they were when I first started my practice.

What kind of initiatives do you guys feel are the most effective at generating new patient acquisitions? What's a Fail-Safe way to rebuild an established practice? Has anyone tried Google local service ads (LSA) with any success? Google AdWords used to work but I found they aren't as effective these days. My practice is straight chiropractic and intersegmental traction. I don't have any soft wave or other additional services. I've noticed a ton of IV clinics in the area as well, but that's not something I've explored. I'm really starting to get scared. Advice is appreciated. Thanks in advance.
