What should i do if i think i have schitzophrenia but don't know how to tell my parents?

Be open with a psychiatrist before consulting your parents. If you think you have it it's best to discuss it discretely instead of out in the open.
Don't self-diagnose yourself,  leave that to the professionals.

By placing 2 fingers at the sternum (the spot where the lower ribs meet) the put the heel of your other hand next to your fingers. hope this
