Hi Rachel,
Don't ever think you aren't forgiven. The Gospel is this and all Christians need to understand this. God, because He loved us so much, gave His only begotten Son, to die as a perfect sacrifice for all the sins of all men. The sacrifice was totally acceptable to God and the Apostle Paul goes to great lengths in Romans 3, 4, and 5 to assure us that we are justified by faith. Easton's Bible Dictionary defines justification as :-
A forensic term, opposite to condemnation. Justification is the judicial act of God, by which he pardons all the sins of those who believe in Christ, and accounts them and treats them as righteous in the eye of the law, i.e., as conformed to all its demands. In addition to the pardon of sin, justification declares that all the claims of the law are satisfied in respect of a justified person. It is the act of a judge and not of a sovereign. The law is not relaxed or set aside, but is declared to be fulfilled in the strictest sense; and so the person justified is declared to be entitled to all the advantages and rewards arising from perfect obedience to the law (Rom. 5:1-10).The act of faith which secures our justification secures also at the same time our sanctification; and thus the doctrine of justification by faith does not lead to licentiousness (Rom. 6:2-7). Good works are the consequence of justification (6:14; 7:6)
Good works must never be considered in connection with bringing about our justification. The only 'condition' for your justification is faith, but that is also all God's doing. It is purely a gift, all of God, all of grace, all of His love and all His doing and all His plan before the foundation of the world. You are a child of God because He decided in His wisdom way back then that you would be eternally His. To doubt that is to doubt His love and His wisdom and His sufficiency.
The angels in heaven rejoiced when you turned to Jesus and asked Him to save you. They are still rejoicing now. FJ
