I've held my tongue because I'm not entirely sure how to say it without being offensive, but I'll give it a shot.
You're young, you're still in school, and you still live at home. Your writing skills are severely lacking in the grammar and punctuation department. That might be out of your control, I don't know. BUT with the way you present yourself here it's unlikely that at this point in your life, if you were of age to be on your own and trying to hold down a job that you'd be able to find anything that pays well enough to support a family. I've said it before, and I'll say it again. Get a good education. Overcome any learning disabilities as best as possible IF you have them. Raising children is extremely expensive. Setting yourself up for success will go a long way when it's time for you to settle down and have a family. Women want a man who can hold his own and provide for her even if she's self-supportive.
If your mother refuses to allow you access to mental health care, talk to one of your clergy at church. Many pastors/priests have professional training in how to counsel their church. You don't even have to mention that you're trans, but you can let someone know that your life right now is difficult for you. It sounds like you could really enjoy the enrichment of having someone to talk to, so reach out to the people who are there for that specific reason.
How do you get over the dysphoria of listening to women talk about their female parts? You just have to work at it. It's a never ending process to grow and mature past what we were yesterday and the day before. It can be really difficult, but with practice it can get better.
You want biological children - so many people out there want to breed and reproduce and so many of them can't. Life sucks. We have to play the cards we were dealt and sometimes we have to compromise on our desires in order to live in reality.
