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.
Also, the fact you are already worrying about providing for your Mom when you are older makes me wonder why you feel this will be for YOU to do rather than your Dad? I grew up in a dysfunctional family trying my best to be perfect and cause no waves for anyone. For a long time I felt responsible for everyone and everything...including holding our screwed up family together.
You are so very young and have your whole life ahead of you. If your parents won't listen to you, maybe you could reach out to a guidance counselor at school? Or if you have your parents make an appt for you with your family doctor for something...then when you are there explain your concerns to them. They will certainly listen and hopefully steer you in the right direction.
My thoughts and prayers are with you. Hang in there.
