I congratulate you on your entering Islam, the religion of truth and of sound human nature with which Allah created His slaves. I ask Allah, may He be glorified, to make you steadfast in adhering to His religion and to protect you from the evil of the devils among mankind and the jinn. I ask Allah to make the life easy for you.
With regard to your disbelieving parents, you have to honour them, uphold ties with them, and keep company with them on a basis of kindness and at the same time keep away from shirk. Allah, may He be exalted, says (interpretation of the meaning):
“And We have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years give thanks to Me and to your parents, unto Me is the final destination.
But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not, but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do.”
As Allah said "repentance" is the key. So always ask Allah for forgiveness. Try to talk with your parents, respect them and show them that you became a very good and respectful person. So they will understand you and accept you when they found out about you that you accepted Islam. May Allah make things easy for you.
