I’m going to make some assumptions here, based on what I remember about being 13 and “different.”
I imagine that it is almost overwhelmingly frightening for you to try to get anyone to take you seriously about something so “wierd.”
I also imagine that you are probably being way over-sensitive to what other people think about you. Looking back, I know I was; but I couldn’t see it then. Try to keep in mind that your friends are probably just as worried about what you thnk of them.
I live in Colorado; send me a private message if you do, too. I’d be happy to take you to confession, or church, or the diocese. I mean it, and I don’t care if you are two feet tall and green. That means don’t worry about whether I’d like you or not.
I recommend saying the Chaplet of Divine Mercy. You don’t have to say it out loud; if the devil tightens your throat, say it in your head. It is a big help to me; it helps me trust in Jesus. If you’re not familiar with it, look here:

Read Matther 4:1-11; it’s the part where Satan is tempting Jesus. Ponder it in your heart.
Last but not least, do some small, nice thing for someone else (especially your mother) at least once a day. In your mother’s case, it can be something as small as not griping when she asks you (or tells you!) to do the dishes. Or figuring out ahead of time that she’ll be asking you to do something, and doing it before she asks.
This is both spiritual exercise, and defiance of the devil. You can bet he doesn’t want you to be nice to your Mom.
I’ll say a Rosary for you tonight.
