Getting RIF's is the first day of the rest of your life. A couple things...
Saw a great post somewhere (maybe here) about setting expectations. You may not get offers at or above what you're making now. But this person's advice was to consider your severance as a buffer to bring you up to where you are now.
Recruiters and employers understand that people get laid off. What's harder is staying in the same position for years without any pay increases or promotions. In some states they can't ask you about your salary, but they can ask you about staying in the same role for years. So be prepared to answer that.
From personal experience, I'd take at most 4-6 weeks off before getting back into the job hunt. Longer than that and you're not as attractive to recruiters and employers.
One thing that saddened me was that I only heard from a few of my colleagues after I was RIFd. I was astonished at how most pretty much ghosted me. So don't be surprised if you don't receive condolences and well wishes from your colleagues and work friends.
