Being funny is the way I cope with my depression but my mom thinks I'm being immature and when there is a problem and i am speaking seriously she doesn't give me a chance to talk/ sides with my siblings no matter what. What do i do?

Eat some cereal and a banana

Think about how you relate to Cinderella

Wait for you to be eighteen so you can leave your mother and siblings and embark on a journey to balance the chemicals in your brain  and be happy and prove your mother wrong. You may also, again like Cinderella, wait for an amazing prince(ss) to fall in love with you so you can make your mother jealous.

I'm in phase 3 (my situation is similar but not the same) lemme know how it turns out.
