Hi, welcome to Spider ID. I’m sorry to hear about your situation. Do you still have the spider? Turn it over and look at the ventral side, is there a red or orange mark there? Your spider looks like it may be a dark variation of a Brown Widow (Latrodectus geometrus). If you still have it and want to submit another image of the ventral we can also compare it to a Western Black Widow (L. hesperus).
