Unfortunately it is true that you can only gain an independent residence permit as spouse after three years of marriage (§ 31 Abs. 1 AufenthG). There are only some limited cases in which the three year rule does not apply e.g. in cases of extraordinary hardship (physical or psychological abuse) in which staying in the marriage cannot be expected of the individual as it would be a threat to their own life. Not knowing the specifics of your situation I would guess that a residence permit based on your marriage might not be possible now.
However you could check if there is any other residence permit that applies to you for example work as a "qualified worker" according to § 18 AufenthG or if there are obstacles to your deportation that require you to stay in Germany. I would advise you to seek legal counsel with a lawyer or a specialized office for refugees in your area fast to help you with the appeal and the steps outlined above, as there is not a lot of time left.
