That's tough man, I'm sorry. It's all up to you, I don't know what year you're in so I don't know how long you would have to stick it out but just do what you think is best. I personally would fight it. I've hear of a few bio girls getting on the boys football team in the past because girls football was touch, not tackle.
Maybe if you researched cases like that you could build an argument, (more like a group of reasons) including being a trans guy forced with the girls, as to why you should be allowed on the guys team? If it's what you love just don't give it up even if you have to find another place to play unless it's what you truly want. Just my advice.
Good luck
