Hi Ray,
Hopefully by the sounds of your recent posts, your parents may be coming round just a bit. I certainly hope it continues. As you are over 18 years of age, Australian Law considers you and adult, and as such, are not legally bound to your parents or guardian.
If not and your father or mother, or for that matter, any family member, threaten you with violence, physically hit you, or attempt to bring you back home by force or Police intervention; you by rights, can take out an AVO (Apprehended Violence Order - see definition below) against them, from your local court house
(AVO - definition. An injunction is an equitable remedy in the form of a court order that requires a party to to do or refrain from doing certain acts. A party that fails to comply with an injunction faces criminal or civil penalties and may have to pay damages or accept sanctions. In some cases, breaches of injunctions are considered serious criminal offences that merit arrest and possible prison sentences. A court may grant an AVO to a person who fears violence, harassment, abuse or stalking. A court may issue an AVO if it believes, on the balance of probabilities, that a person has reasonable grounds to fear personal violence, haressing conduct, molestation, intimidation or stalking. A defendant's non-compliance with the order may result in the imposition of a fine, imprisonment, or both. Ref: Wikipedia.)
I tend to believe from your previous posts, you have adequate evidence to secure an AVO against your parents. In NSW, you cannot be involuntarily institutionalise without a court order, even then you have to sign the admission papers which includes a declaration stating that you are admitting yourself. If you live close to Sydney, the Gender Centre in Petersham (029569 2366) can assist you with Doctors, Therapists, Counselling, Housing and many other forms of assistance. If you live in another state, they will have similar Gender support organisations. Again the Gender Centre in Sydney can advise.
GID is a tough road at the best of times. The harassment you have experienced is totally uncalled for and unrealistic to be subjected to, on a daily basis.
I do hope you are able to make some good headway very soon, for your own health and wellbeing.
Be safe, well and happy
Lotsa huggs
Catherine
