Mental health

I don’t know if I am the only one going through this but my mental health is off the roof, I am trying my best to get it under control. I feel so inferior, I just want to disappear. The pressure on young people to make it is too much. I’m just 20 years old, what should I be doing with half a million naira phone. I just want to read books and be happy, Is that too much to ask?
