Hi, I know I haven't been posting a whole lot recently, but last weekend something happened. I went to a "Youth Encounter" retreat in our diocese (It's like a Cursillo for young people). It was quite amazing. One of the best things was that only about a little more than half were Catholics. The rest were not. There was a mutual respect for each other's beliefs that I had not been seeing for a very long time in school or anywhere. The whole weekend, I did not hear of one fight, debate, etc... between anybody. It also helped me to get my life back on track a little bit.

Perhaps you should speak with your pastor. If this is interdenominational it might not be the Catholic standard of receiving Sacraments (possibly only having been baptized if you are baptized already). Never hurts to ask.
