SORRY!
Dear friend you will not get to heaven simply because you have "spoken in tongues" because the Bible says:
(2 Corinthians 11:3-4) But I fear, lest by any means, as the serpent beguiled Eve through his subtlety, so your minds should be corrupted from the simplicity that is in Christ. {4} For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
(2 Corinthians 11:14) And no marvel; for Satan himself is transformed into an angel of light.
(2 Thessalonians 2:8-10) And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: {9} Even him, whose coming is after the working of Satan with all power and signs and lying wonders, {10} And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
So you see my friend it is entirely possible for Satan to counterfeit genuine spiritual gifts and signs. Speaking in tongues is not something that is practiced by charismatic and pentecostal churches alone. Satanists, Hindus, Buddhists, New Age cults and many other religions that would be considered cults or anti-Christian practice tongues-speaking as well. That is why nowhere in the Bible is it ever stated that a person will go to heaven just because he has spoken in tongues. I know you don't like to think of the probability that the tongues you spoke were not of God but if you believe that your speaking in tongues ensures you of eternal life you have been deceived.
