I spent my entire youth screaming for attention by doing any thing i could to just get noticed!!!
If they can't take you being melo-dramatic - there is something wrong with them !!! That is my feeling on that subject. You had a need to present things that way. Any adult should be able to have the common sense to se and feel that you are acting that way for a reason that they may not yet understand. The only appropriate response to you ahould be one of inquiry, especially from a parent - otherwise they are not engaging in having a relationship with you - however you need to be. Melo-drama is no worse than happy go lucky. They are different ways of communicating - both can be as fake or real as the other. Neither is better.
It makes me so mad to hear that someone couldn't investigate what you might be having dificulty speaking out!
That is my take on that.
You are a unique human being. If you've got something to say, say it, and think well of yourself while you learn to say it better. (David Mamet).
Great book that captures the truth of PTSD: The Sentimentalists by Skibsrud
