Depression, loneliness, heartbreaks, loneliness, being different from your peers, and having to put up a front; all these situations all give us the same feeling: sadness, feeling that you are not wanted and so on.
Many people think that they are not wanted/not accepted/inferior to the community when encountering this problems. Statistics show that 15% of depressed people will commit suicide. This is an alarming rate, and this happens because people who have these problems do not seek help.
So the most obvious thing to do is to seek help from peers, teachers, parents and if needed a professional.
