Offended over something. My experience?

Hearing people talk about their depression and their " depressed phase " always and never fails to make me feel off and horrible . I have been through a dark episode, where I literally couldn't smile and hope for a good day and I dealt with serious suicide attempts and suicidal thoughts all the time . Yet when I talk to people about it , all then said was " you are a teen it's normal " even now that i am completely healed , it's hard to hear that and be okay with it . Something about that line tells me all this wasn't real and that it isn't a serious thing when I was losing my soul because of it . Does everyone really feel this ? When people say they " feel me " it makes me more depressed . What I have been through was real and painful and i know it wasn't just " hormones " and a " phase " . Can someone explain why I feel angry about that? Why does everyone think they can relate to my experience ?
