I need help to leave my parents' house

Hi, my name is Robin, I'm 20 years old and I am trans. I currently live in Portugal with my catholic parents and my five siblings. My parents always made sure to pass their religious beliefs to us and we're basically forced to believe it, until I decided that I didn't want to follow that religion. Since then, it took me two years to finally leave the church and be free from it. Except they still try to make me go sometimes, which I always refuse. The only reason they let me leave was because my panic attacks were getting really hardcore everytime I put my feet in the church. But still, I don't have a lot of freedom. I can barely express myself and I'm not allowed to bring pagan things to my room, that I share with two sisters.

Recently, I had a talk with my parents who knew that I was trans but never acknowledged it. I tried to be calm about it but it's a very touchy subject for my parents and for knowing it, I always get anxious talking about it. I thought that if we had a conversation instead of a fight, maybe I could make them realise that being trans is something that exists and not a disease. After I told them I wanted to start HRT, reassuring that it wasn't an implusive decision and that I took a couple years to finally make that decision, my dad laughed and told me I wasn't trans. They believe that I'm too unstable and I don't know what's like being a man. After I told them that for the first time in my life I felt stable and ready to make this decision and finally be myself, my dad threaten that if "I insert those drugs in my body" they would kick me out of the house.

I no longer feel safe living here and I feel like they can kick me out any time. My biggest concern is not being able to see my siblings and I'm also scared for them, I don't want them to go through what I'm going through right now. I still need to start saving to get my own house and start a new life. I don't have a job, though I'm still looking for one but it's not easy for a person without a lot of experience, and houses are too expensive for a person working a full time job to live.I'm starting to save money to be able to get a place of my own but if I get kicked out before I have that money, I have friends that can keep me in their homes for a while. I would be so greatful if a few people could help me with my savings, you would be saving my life.
