Hi. I commend you for helping your friend. You may be all she has. At the very least, you both understand eachother. You can't do it alone though, bharani and optimize both have good points in that a professional, even a school counsellor should be consulted.

There is a high percentage of teens that go through a period of moodiness, isolation and have difficulty finding themselves. I think some adults just figure that those feelings are "normal" and don't take them seriously. When something does hit the fan, they are completely floored. Your father may not understand the degree of suffering that you are going through.

Both you and your friend need help to get through this. In addition to counselling you, perhaps your father would respond better if another adult told him that you were depressed.

As a teen, I was very depressed, kept completely to myself, never ate dinner with the family and would just shut myself in my room. My parents never said anything or suspected a problem. When I finally became suicidal, they were taken completely by surprise. i wouldn't recommend that for a way to get attention though. It just brings on more trouble. The point is that for whatever reason, your dad isn't understanding the message you are giving him. An adult authority figure might be better.
