Hey Hannah sorry for an even later reply to your post.
I am single so i can not comment on your current situation however i can comment on your issue with depression.
I was in a bad situation when i came out as trans, i had left where i was living and went back to my parents as i was in such a bad state, i know this tpye of talk isnt really allowed on here but i attempted ‘things’ multiple times until i managed to go to the doctors and admit who i am. Years down the line and i am the happiest i have been.
Long story short talk to a doctor first to kick things off, you will need to talk to your loved ones of course but get advice first x
