Emancipation or notarized letter of guardianship?WYOMING.?

I am 17 years old, 2 months pregnant. Living in wyoming with my aunt at the moment and my boyfriend who is 19. My mother lives in Tennessee and has for 2 years now. She gives me permission to live on my own and with my boyfriend. We are currently looking for an appartment but i must be emancipated or have a letter notarized saying i can live with him. I want to do whats easiest and fastest so i can get stable and on my feet before my unborn child arrives. Tennessee has no statues of Emancipation. Wyoming you can have consent but my mother does not live here and can't get here. So i need to know what i need to do, to get this over with and able to get an apartment before the list gets too long and i'm screwed. I have been living on my own since i was 16. I turn 18 in october of this year, but my child will be born in december and i'm pretty much homeless if it wasn't for my aunt, but she has 6 kids and i can't keep living here. I applied for title 18, but i need to be considered an adult before i can live on my own with my babys father, and to do that, i need some proof. Please help? Only if you know from being in wyoming not any other state. they are all different.
