It sounds like you are looking for someone that you can relate to who is also in school so you can share ideas and conversation with each other. Although information can be shared here, you might find what you are looking for within the walls of your own school. If you have not really found that group yet or that person who you consider a friend, take a chance on getting involved with a club, an activity, a sport, a volunteer activitiy, a school group project, or even an elected position like student council or something. Any of these might give you the opportunity to get to know some friends on a deeper level.
When you do find you are really clicking with someone, set up a social activity with that person. Once you are feeling comfortable with that person, share something personal (just something small not a truly intimate detail). Little things like this build up trust between two people. Eventually you will have that inner circle of friends that you feel extra comfortable with. You have to put yourself out there too though. Take an interest in someone, but also share a little bit about yourself too!
just answer questions and let them know your there as a friend to help also ask questions that you need help with. we are here to help you as much as we can this is what friends do. hope this helps. here is one friend at least. smiles!
