First off, I'm sure you're not alone but it may feel that way right now.
I am guessing you're a teen, and that's hard enough without adding trans on top of it.
This isn't really a trans forum although there are people who will listen with a sympathetic ear (and there are people who won't, so be aware of that). I did find this good resource which may be of help to you - http://www.tsroadmap.com/info/transgender-forum.html
In the meantime, is there at least a trusted teacher you can talk to? Someone who can be there for you in person and lend a sympathetic ear. Someone to be kind.
Teachers in particular are used to working with teens who are having issues at home. It's not a perfect fit to your situation but it is an aspect of it.
I wish you well.
