Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

Getting access to help is important. Do you have regular doctor appointments? (once a year, every 2 years, .... ) If so, then please bring it up with the doctor. You can ask your mother, or who ever takes you, for a private moment with the doctor. (t may be easier if you have your dad take you as you can just hint that it involves women stuff and he will likely be more than eager to leave the room.)
Changing your parents behavior can be done, but it will take time. sometimes it is best done in small efforts rather than one huge effort. For example, get your father to the point where he knows you need to talk to him is a first step. Actually talking to him about deep feelings is another step.
Something like "Dad, I really need to know that I can talk to you about important things. Mom seems unwilling, so I need you. Please think about this, and then later we can talk more."
Then leave. Let him work on it.
Then when he seems more willing to listen (and he may be more curious about why you phrased it the way you did), you can approach him again. Perhaps talk to him about something unrelated to your real fears; maybe ask him why boys sat things the way they do. (Have an example ready.) Then maybe something else (perhaps a day or so later) that is natural for him to have opinions on.
Gradually work into your real needs.
What you are doing is conditioning him to talk to you, and giving him some early "successes". By time you are ready to continue gradually into your real needs (do NOT drop them all on him at once) he should be used to talking to you rather than trying to shuffle you off to your mother.
The same thing may work on your mother, but my completely unfounded hunch says she will take a different method. But if she sees you getting chatty with your father may make her want to be part of things. Equally as unfounded is my suggestion to skip the "gotta talk to you" part with your mother and just work her up to talking about issues that are not that important to you so that she gets used to talking about "hard issues" with you.
Gentle hugs
