Paranoia: This is best evaluated by your physician asap -- physical exam, labwork, and a proper referral will be of help to you.

Certainly: Please be kind to yourself and your loved ones(&pets). Tomorrow make an app't with an excellent psychiatrist. You can & will be helped. Check with the closest medical school or call the american psychiatric association in new york. Maybe even better contact your closest medical society.
