Shallow gal: everyone in my grade knows how, but I can't swim--and swimming is required at my school. Can you give me tips so I don't have to take a baby class?

Take a deep breath (before hitting the water!) to calm your anxiety. As with anything new, don't immediately dive into the deep end. Start in shallow water with the basics, like holding your breath underwater and hanging onto the edge while kicking your legs. You're not the only girl who doesn't know how to swim but, to kick up your confidence, consider taking a class at your local Y or rec center. There are courses for beginners--no babies allowed!

When I make a new friend, my BFF takes it personally. She says, "you'd rather talk to her than to me!" and stays mad for several days. What should I do?

Clinger alert! Having a clingy friend is a compliment to how great you are to hang with, but it can be frustrating. If she panics when you hang with new people, tell her it doesn't minimize your friendship. In fact, it might make it more fun. Include her in some plans with new friends so she won't feel left out. If she still overreacts, distance yourself from her controlling ways--and tell her why. No one should be limited to one friend.

My BFF is a guy who used to be my boyfriend. I miss him as a BF. I think he's giving me signals lately, but I'm not sure if I can trust my instincts. If I were to act on it and it wasn't true, I'd die of embarrassment

Being friends with an ex is tricky, and things can be extra complicated if you still have warm feelings for him. If you don't want to confess right away that you want him back as a BF, first address the way he's been acting. Tell him a certain thing he does seems flirty, then ask if it's intentional. You both need to be on the same page, whether you're in a relationship or friendship. The only way to find out where he stands is to ask him.

One of my friends lies a lot. She even stole some of my things and lied about it. Should I stop being friends with her? I just don't want to be mean, but I also don't want to be too nice.

Even if your friend doesn't mean any harm by her lies, you should in no way ignore the issue, especially since she is also stealing. Her habit of lying and lifting stuff spells trouble. You shouldn't have to deal with a friend you can't trust. If you like her and want to salvage the friendship, arrange a time to sit down alone with her for a talk. You don't have to be mean or nice when you confront her--just be honest. Tell her you're concerned about her actions because the friendship means a lot to you. But let her know you can't stand by a friend who lies and steals. Lay down the law: If she doesn't change her ways, you cannot remain friends with her. If she agrees to rein in her sticky fingers and loose tongue, give her another shot. Otherwise, it's time to end this friendship.

THAT'S A TOUGHIE ...

I found some pills under my brother's mattress, I'm not sure what they are. If I tell my mom, she might be mad at me for going through his room.

Even though your mom might get mad at you for snooping around in your brother's room, you must put his health and safety first. 'Fess up and tell your mom what you found. It's up to her to handle the situation from there.
