Struggling with demons

I am FTM trans, 27, pre-everything, and I've been struggling with my own demons for 2 years since I came out to a few people. The thing is, reactions of them are supportive because they are friends, I live as a man since then, I totally like it and I can say I started to be happy for the first time in my life and I am pretty successfull to pass as a guy, which makes me quite comfortable with myself for the first time. BUT I dont have a courage to take another step for transition. I live in a very conservative catholic country, there are problems with it in society and doctors and moreover after transition I would live openly as gay with my boyfriend (which is our common nightmare, but he supports me anyway) - now I have female name and nobody can say a word even though I look as a boy. I am not able to overcome fear of what would happen in the worst scenarios. I would be treated badly at university and work, bullied, laughed at, family would turn its back on me or they would treat me with contempt. And there will be no undo. Detransition is the most humiliating thing I can imagine. I am afraid I won't be able to fulfill demands and expectations as a man. I know maybe anything of that would never happen, but I am chased by guilt, confusing thoughts, fear and anxiety.
If there's anybody who would like to talk about it, I'll be glad, I'm leaving my contact
