How can i ( a teen ) live a christian life ? and get over my hurdles ?

hi, for many years i have been saved and for many years i have back sliden, i was raised in the church, and my mom is a youth pastor and opening up her own church very soon. I really try to live the way God wants me to but there are these periods of time where i give up and live a worldly life. I know the end is coming near, and i want to make sure i am ready. Being a PK ( pastors kid ) everyone expects for you to be perfect, but the truth is i am not, it is hard to go to someone for advice without being judged, and it is especially hard to go to my mother because of her high expectations. I REALLY WANT TO CHANGE and live a true, genuine, and full christian life. I have been saved and said the prayer ... but i cant figure out what to do next ... some wholesome advice would be greatly appreciated, do you have any devotional recommendations ?, anything would be useful. also some of my main problems are 1.) secular music 2.) letting go of friends 3.) trying to be a people pleaser ( changing myself to fit other peoples ways ) and 4.) lying . i am really putting all this out there because i really want the help ... thank you
