There's no magic way to get people to use the right name but your options are probably 1. (politely) repeatedly remind them of your preferred name, to give them the message that this is important for you and them ignoring your request won't change your mind on it; and 2. (for doctors) make a complaint, there should be somewhere on their website that tells you how

And where to find friends - lunch/after school clubs, outside clubs for activities like crafts, music, games, sports, youth groups, see if there's a trans/lgbtq support group near you. If the problem is that you find it hard to make friends, my advice is look for someone in one of these places your age who looks like they also find it hard to make friends and literally go and say hi and start talking to them, see if you have an interest in common

I'm going to attempt at this but please I'm no expert. The first thing you'll have to do is recognize you can't change people. Not your folks or friends or indeed strangers. Don't even try ..if they cared they would respond with kindness and respect. The good news is, you can and should focus on yourself. You have to develop a thick skin and stay true to you . Being Trans is not an easy task especially in this political climate. People from all walks of life will probably try to make you doubt yourself and deflect you from your truth and path ! That's unfortunately where we're currently at in society. Your best defence is probably self confidence and calmness. Don't get drawn into drama and circular arguments . Just be safe and be yourself. Those who are supportive will come to your side and those who can't tend to vanish out of your life. It's brutal sometimes but nevertheless you will discover who your true allies are. Treasure them because things can get rough sometimes. Your Dr is another matter. They have professional standards that they must adhere to. I don't know your exact age but I'm assuming still considered a child. In which case refer them to the "childrens charter" and remind them that your opinions and feelings must be taken into account. They can't just bluster over your head. Have you asked to be referred to a GIC (this request goes onto your records and in itself evidence of your needs) If you go to your doctor's office independently you can speak with the practice manager and ask if they can put a note on your records your preferred name and gender. I don't know if without a deedpoll they're obligated to, but it's little wins like this that will keep you going. Ultimately, congratulations for choosing your own path ♥️ have an amazing Christmas and smile, it's going to be fine you'll get there. X

In answer to your question regarding your parents, give them time, remember it is a big adjustment for them too, they have called you by your name and known you has there son for 15 years. Try not to get angry with them, I understand it is frustrating for you, but just politely keep reminding them and have a little patience, it will work out right in the end.

Not sure. I believe you have more rights at 16 to have your name changed, but it might involve parental consent still.
