Struggling with sin and I’m going crazy

I don’t know whats wrong with me. No matter how many times I say its the last time I’m going to fall into sexual sin, every week I end up doing it. All it takes is literally a thought. To make things worse I got baptized just this last Sunday, and here I am sinning. I have no idea what to do and I can’t keep going on like this. To make matters worse, I lost all my friends and I’m in a household where my parents don’t like me going to church, so I’m all alone and I have no one to disciple me. I was in a church before at university, but my problems of depression were too much for any of the staff to help me, and I just feel like I am beyond saving and I’m going to be alone for the rest of my life. I genuinely don’t know what I’m supposed to do. I tried praying and going to God about it, but I get nothing. I give up.
