Firstly, welcome to the forums we are so glad that you found your way to this supportive and welcoming community. We hope that you find ideas, options and support from the shared experiences and knowledge of all our members.
We want to thank you for having the strength and bravery to share your story and allow our community to help you on your journey. We can hear that your dad is having trouble accepting who you are, resulting in him taking out his frustrations and judgements on you. This must be overwhelming when you are already trying to figure out yourself, school and future planning at your age, with all of this we hope that you are taking time for yourself to unwind or do an activity you enjoy.
As stated by ‘That Other Guy” it sounds like your mum is accepting and is the best person to seek support from at present, do you have other friends or family that are supportive and understanding?
We would like to acknowledge all the great advice and suggestions that have been recommended so far and would just like to add some in case you do feel the need to reach out for more assistance or advice. As recommended by Geoff we will also suggest Kids Helpline as a great point of contact, alternatively we want you to know that Beyond Blue are there for you if you need to talk anytime.
Beyond Blue support service 24/7, either via phone 1300 22 4636 or web chat: http://www.beyondblue.org.au/get-support/get-immediate-support
We would also like to recommend contacting QLife. QLife is a free and anonymous service run by LGBTIQ+ peers for those wanting to talk about a range of issues including sexuality, identity, gender, bodies, feelings, or relationships.
