Dear Miri93, I'm glad that you're going through the transformation process as a born again Christian. You're putting Jesus first in your life (See Galatians 2:20) and doing God's will, not your own will or desires. The Holy Spirit will help you to transform; it's a journey. You still might sin from time to time, but it will be less and less. The Holy Spirit will convict you of your sins and you'll have a strong desire to repent of them. He will guide, advise, and counsel you. I wish you all the best in your dedicated Christian life. In Jesus's name, I pray.
Miri93, I am praying for you
