I'd be in a psych ward if people knew...
What would you be in a psych ward for?
For how much I hate my dad, due to how strict my parents are.
Everyone hates their parents from time to time, so this doesn't make you crazy.  However, your parents are just looking out for your best interests, even if it makes you really mad, so you shouldn't resent them for it.
They take everything I do seriously, I wish they'd lighten up.
Have you shown your parents that they can trust you? If so, as you get older, you should talk to them about how you need more freedom so you can grow as a person.
