I know how you feel, because it sounds like how I used to think. You think that people won't accept you and reject you out of spite right? That all your friends will disappear? Don't, you are worried a little to much.
For one, i'm military, i've told plenty of people I felt needed to know. Each one of these people could have had me dishonorably discharged before the week was over. Thing is, they didn't, not one. In fact, even though they didn't even understand what it was exactly I was dealing with, they listened, and even tried to help.
My best friends have also listend, one being your typical by-the-bible girl. She not only accepts me, but is even willing to help me with my trasition.
My family was harder. Like your mom, my mom is very set in her thinking. Unsuprisingly she rejected the idea right off, along with my dad. But as time goes on she sends me letters, even insperational storys that shows me she is slowly coming to accept the idea. I'd would have been worried if she HAD just accepted this.
Just slow down, take a breath, then take another. We all know how hard this is going for you, so let us help. Many times I felt like there was no hope, so I turned to the wonderful and often wise people on this site.
As my grandmother said, "If you quite, you never see the ending." If you give up on life, you give up on every hope of achiving your dreams. So again, slow down, get some sleep, tomarrow is another day.
