<p>It is normal to be hesitant about new social situations or of possibilities that appear scary.</p>
<p>Nevertheless, I urge you to try something along the lines discussed above. Start small; after small successes your confidence can grow and you can move on to bigger things.</p>
<p>But, if after some time of trying, you find it impossible to even get started, then I would recommend that you consider talking to a therapist, perhaps at your school. A therapist would talk everything over with you and help you to get started.</p>
