Purity Advice (Catholicism)

Hello! I’m Catholic! So today I had sex with a guy friend I know. I didn’t go all the way, but now I feel guilty and just ashamed of myself. I know my purity is not defined by my actions but at the same time in my religion, Catholicism, Sexual activity outside of marriage is a serious sin and Im tired of living like this. I go to confession for the same thing over and over again for my impure thoughts and I want to get out of this trap the devil has me chained to. I really want to turn my life around and be the happy and fun loving young woman I always am but knowing that I’m not being blindsided by the media and that my relationship with God is secure. Any steps on working for that closer and deeper relationship with God? I am a freshman in college. I know that God knows my heart and knows that my actions do not truly define who I am which is why I want to change them, bc the devil is making me believe those actions do. I joined the Catholic Student Association on campus and will be attending my first meeting with the group this Wednesday. I also plan to go to mass on campus after class Monday and schedule an appointment for confession as well as just a spiritual talk session with the priest at the campus church on Monday as well. I want to turn away from this sin and start living a life of Christ like I claim to live. If anyone has any advice for me and any steps or songs/Bible versus/blogs and articles for me to read, all is welcome! I do ask however that you please do not comment on this if you are going to say “you can do whatever y out want bc God saved you already” or something along those lines. bc that is not necessary ot true and I do not believe that. I also ask for your mercy and understanding and no judgment because as Christians we are called to love and understand not judge and hate! Thank you!!
