What's my issue lately?

I have/always will be a chrisian. A devoted one at that. Now i posted a question asking if spells and stuff is a sin. And everyone freaked out pn me. 1st of all it was an app and I was just having fun. Also recently for the past 2 mts I have been cursing/using vulgar language at school. I hung out with the wrong crowd an started to lie. So im trying to get away from the bad ppl. I also bought 4 thongs (ima 7th grader) and I feel guilty. I feel like God doesn't accept me and is pushing me away. I believe in God 100% and I don't get why all this is running thru my head. Please help me reassure myself that I am a believer. And also give me tips to be clOser to god
