I didn’t realize it until after my dad’s death. My dad always knew I had some sort of mental illness starting my middle school days. He wanted me to get professional help, but my mom refused to let me get that help. And until after his death, that is when I realized that I was depressed. And that I was struggling with mental illnesses. My psychology classes also helped me realize that I was struggling with them. If you feel like you are depressed, then you may be so. You should get professional help and ask them for their opinion. Hang in there.
