Deleted entire email inbox by accident

Can you please help me? I accidentally deleted my entire email inbox last night for sherry.heil@comcast.net. 

Have you tried the Trash folder and "Recover Deleted Items"? Messages deleted from Connect folders are moved to the hidden Recovery folder and are kept there for 30 days, or until the folder contains 15,000 messages, whichever comes first. During this time messages can be recovered (see https://connect.xfinity.com/appsuite/apps/faq/index.html#recoverEmail).
