How to not be shy? or annoying? or intimidated?

[Natalie]

hi I'm 15 and I go to a new school, kinda. I've been going here for a year but I still don't know people. I'm in a sport and I have practice every weekend. the coach pokes fun at me because I never talk. it's because I don't have anything to say, or I'm intimidated. usually I will stand there thinking of something I could say, but I don't know what to say. I try to ask more questions and be a good listener, but nothing comes to mind. anyways, on twitter, I'm really outgoing, I speak my mind and I tweet a lot. I've been loosing followers (the kind that go to my school) so I stopped tweeting my hilarious tweets and such. I don't tweet too constantly but If I am on twitter and bored, I will tweet every ten minutes. and I hold small talk too. but help me. people on my team have actually blocked me. I don't know if it's because I'm annoying or if they jus don't like me. maybe they think I'm snobby because I never talk? I had some self confidence but it's when I'm around my team or people from my school I get intimidated. HELP

When you're thinking of what to say you should be thinking of how you are on Twitter and just release the energy
