Consult a lawyer, or a fortune teller. Nobody else can tell you that.
is it possible to appeal?
Not really, unless you can prove that the office for foreigners did not act in accordance with the law, and that's very difficult to do. Without a legal basis, your appeal will not be accepted for review, and you will have to return to your own country. You can't appeal simply on the basis that you didn't like the decision. Nobody cares what you like, or don't like. You have to have a credible and plausible legal reason.
