Answer: Unfortunately, this really does not sound good at all. The exudate or gummosis could be the result of borer or other damage to the trunk and sudden wilting is often a sign that the tree is dying. I would strongly suggest you work with your local professionally trained and certified nurseryman and/or your county extension or possible a professionally trained and certified arborist to check the tree and see if there is any hope. I'm so sorry.
