Feeling lonely.

I'm really feeling lonely lately. In the weekend, there's nothing to do and I don't feel like asking a friend to come over. It feels like they're all busy anyway. Also on facebook no one replies to me these days. And I actually only have 3 real-life friends, and they all live far away. 30 minutes, 1 hour and 13 hours. I just feel totally forgotten and I don't feel like trying to get any more friends now. :/
And I've been thinking a bit... I'm not really active. I only have voice-lessons, that's it. Yeah, my mom took over the piano lessons. I like playing the piano, but I don't like the lessons. So I decided that if we're getting a digital piano, I'll definitively practice, but if not then that's okay, then I'm just not going to play the piano. But then again, it's not really something 'active', it's not a sport. Yet I'm interested in quite a lot things; Snowboarding, basketball, jazz dance, hiphop dance and kinda parkour as well... I'm thinking about doing hiphop dance next year, but I'm kinda afraid of asking my parents right now and I'm not sure if it's something for me... If it's something I like...
