I wish I could give you something a bit brighter than what I am about to say but its the truth... You have 2 options. Tell them and deal with whatever comes your way as a result, or don't and learn to deal with it until you can get on your own and then transition. Those are your options. Now Firstly (assuming you are in the states) your parents cannot legally kick you out and assuming you really want to you can make their life a living hell because in most cases depending on what they do it can be considered abuse. If you file for that, they will send you to a mental health professional to evaluate you for the abuse and if they did then they get charged with it. If they throw a fit, and you choose to do nothing then you will be stuck in the situation they present you with. Given the things you fear would it be so bad if they kicked you out or disowned you? If they aren't going to help you and are going to make your life hell are they really worth having around? What you are facing right now is what pretty well all of us have faced, the same thoughts and same issues, the only way you will know what they will do is to flat out tell them. Don't beat around the bush, don't leave a flowery note, come flat out and say mom, dad, I am trans and I want to transition into a boy. I need your help. Will you help me? Then deal with what happens after as it comes.

Flat out, it is an uphill fight through the entire process, you will have constant medical visits and bills associated with the hormones and the level checks, you will have to deal with any surgical stuff you need (hysterectomy, mastectomy, so on), therapists and their costs, dealing with school and the kids at school, society as a whole depending on where you live, your family, there is absolutely no part of this that is going to be easy. Is it doable? Yes, there are a ton that do it every single day, you just have to get your head out of you and focus on the big picture. How are you going to pay for all of this? If you aren't focusing on education and a really good paying job for 10 years from now, well you may be setting yourself up for failure regardless of what happens today. You also need to focus on what is REAL, not what is fake. You can go and bind, change what you wear, do whatever you want, you're still going to be you and until you can learn that the outside don't mean carp, but the inside does, you will still go look in the mirror every day and hate you because you never learned to love who you are for who you are. I went the reverse route from you, I am 40 years old and started at 32. In my head I am a repressed 20 something girl who yearns to be some pretty little college girl, but the reality is, I am a fat old person who has 32 years of testosterone to overwrite. I will never be what I see myself as, but that is okay. The reason why is that I am not defined by a pair of heels, a dress, perfect skin and hair. I am defined by who I am in side, I know I am a woman, I know who I am, and as such not one person ever misgenders me even if I don't pitch my voice up. You can go ahead and strip all the makeup shave your head completely bald, wear boxers, jeans and a tshirt all you want and bind yourself flat as you can, you will still get misgendered until you have found a way to love who you are and be a man regardless of the dress and heels or the tennis shoes, pants and tie. I am going to send you a message as well because I don't like personal details in public forums so please read it.

My advice would be to tell them. My son was afraid to tell me at first. He was also afraid I wouldn't understand - but he was wrong. I already knew something was going on with him and when he finally came out and told me, the pieces of the puzzle just all came together.
Take the chance and tell your parents, but do it in a non confrontational way. Maybe this will help them better understand you and why you've been pushing back on so many things lately.
I don't know your parents so, this could go either way, but it doesn't sound like you have much choice at this point.

As a mother of a ftm teen my advise is to tell your parents. I still love my child just as much, I still support her and treat her the same as before. Nothing about my love for her has changed. I hope your parents will be as understanding.

Hey, i understand you because im kind of in the same situation. I had told my mom about me being FTM and when i told her the first time she didn't accept, so i let time go by and i recently told her again and this time she looked more accepting to it. I have always felt uncomfortable being in the wrong body and she's open about me dressing like a boy. I do plan to transition because i want to be comfortable in my own body and actually be who i am.

How old are you? What did your mom say when you came out the first time? Like specifically?
