For anyone concerned after I mentioned the threat against my synagogue, the FBI figured out who made it, and it turns out it wasn't a threat. The person who made it has a mental illness that features hallucinations, and they had a vision of the temple being attacked, and called to warn us. Since this person is well meaning, and severely mentally ill, no charges are being filed, and hopefully, the person involved will be able to get the treatment they need. Anyway, this means I will be going to Erev Yom Kippur services this year, though the full Yom Kippur service is still too much for Mom's health. She's doing very well, by the way, and recovering from the lung disease with very little scarring, but she still thought it best we pick the shorter service.
