Hugs, Skyler.
First, please give yourself credit for dealing with a very, very difficult situation. Living with people who disapprove of your very being is crushing and disheartening, even if they are your family. We all need validation, and you're in a position where you don't get much. Dealing with the dysphoria of not living as your true gender is hard enough for someone who has the full wherewithal to transition.
I don't know you, so I don't know what advice is good or bad. So I'm going to throw everything I've got out there, but feel free to ignore what isn't helpful.
1. It WILL get better. You are depressed, and depression is an illusion that your past, present, and future are all awful. In fact, you have some control over your future, and you have within you the strength to improve things.
2. Do what you can to educate your family. On the one hand, they're religious, so it will be an uphill battle, but on the other hand, if there is love there, they will not want to harm you. Your job is calmly to help them understand how much their lack of acceptance is harming you. Try to remind them:
* You did not choose this. You were born this way.
* Transgender is serious. People who are prevented from treating it suffer severe anxiety and depression. By not supporting you, they're driving you into an unbearable place.
* You simply can't "decide" not to be trans. No one has ever been able to "cure" it, and it typically doesn't go away on its own.
* Their treatment of you is destroying you, as surely as if they were burying you alive.
It's going to be a long road with them, but if they truly love you, they can be made to see what they're doing to you.
3. At the very least, don't let anyone stare you down. You are an adult. You have the right to come and go as you please, to go where you want and do what you want. No one, not even your family has a right to tell you where you can and cannot go and what you can and cannot do. Remember that.
4. Do you have a friend who can be an ally? If not, do your best to find one. If there is a PFLAG or some other LGBT support organization in your area, try to make contact. If not, look for liberal organizations, like Unitarian, UCC, or MCC churches, Democratic clubs, or any other place where people hang out who are socially liberal. It would really help to have someone who can help you get places, find a job, or, if necessary, a place to live and a way to go somewhere more accepting. The world is full of accepting, giving people but in some areas, they are harder to find.
5. KEEP POSTING. There are many, many caring people here at Susan's. PM people who seem to care. Try to make contact with people. Have people to reach out to when things are really bad.
6. Find things that help you feel true to yourself. For me, those are reading, writing, walking, and listing to music. For you they'll be different, but find what those things are and do them as often as you can manage.
7. Look for ways to bring joy to others. It's surprising how much this change in mindset can help reframe your mood.
Hugs, Skylar. I know it looks dark, but you are not alone, and you are strong.
