I don't have any practical advice about reaching out re: waitlists, but I will say that I'm sorry about the waitlist result and totally understand the sense of it being a bit of a mixed bag in terms of how to feel about it. I'm still waiting to hear from Berkeley (like you - my top choice and the longer I wait, the more anxious I become even though I know that's not going to change the situation at all).
Wishing you all the best of luck hearing from the rest of your schools and I hope you're able to lean on some friends and family, even if it does have to be virtual for the time being!
