Poor Tussie! It definitely sounds like something is wrong. She may have a tick-borne disease of some kind (even if she tested negative for Lyme disease, there are many other possibilities), a systemic illness like liver or kidney disease, or a neurologic disorder of some kind. It sounds like she's been to the vet somewhat recently for heartworm and Lyme disease testing, but I would recommend taking her back for a recheck since it sounds like she still isn't doing well. She needs a complete neurologic exam if she is still acting drunk and having balance issues, as well as a thorough otoscopic exam (possibly under sedation, if needed) since middle/inner ear infections can also cause the symptoms you describe. Blood work and additional testing for tick-borne illnesses may also be helpful if nothing else is found.
