Help please

I was raised catholic, I believe in god, but I don’t go to church and I like to pretend I know everything about god and tell my friends to pray, when I really don’t know myself, I just want to believe that I’m catholic when I don’t know what anything means, I pretend I do when really I’m not sure. Please help me, educate me or something. I’m 16 and confused on life, please don’t say anything negative. I have anxiety and I get triggered emotionally/mentally sometimes.
