Trans and alone

Logan

So I came out as a trans male to my family and wanted to start t and everything and my family and friends were ok with it. As so as I told them what my new name was and that my pronouns are he/him they said it’s just a phase. So now I’m all alone in this and stuck in the first stage because my family cut me off after saying I was really going through with it. What should I do I feel alone and that nobody supports me or wants me to be me.
