Thank you for reaching out to us! I totally get what you mean about your thoughts, and honestly, you're not alone!
I believe the determining factor in seeking help is when something disturbs and causes distress enough. A lot of individuals don't seek help for certain symptoms of an illness because it doesn't bother them (enough).
So ask yourself this: Are you troubled by everything you stated? Does not fitting in to societal standards bother you?
I have come across many people who come for assessment as they are concerned that they may have mental health issues. While some truly are facing issues in life, others may just be normal variant. :)
Please rest assured that any consultation with a psychiatrist (be it in public or private sector) is confidential. That is, your records will not be revealed to anyone unless you have given your consent.
That said, if you're still concerned about 'leaving a record', you can consider going to the CHAT hub at *Scape to find out a little bit more about mental health issues youths face today. This service is provided for by IMH, and is targeted at youths aged between 16-30 years old.
Good luck!
