I'm really looking for some support right now; I know I'm sort of venting here, but I really need to vent right now

These past few weeks have just been hellish. I've always been dysphoric, but lately...It's like it was for me during my last year of high school all over again; when I was certain that I needed to do something, but powerless. I left for college, with a more femme identity and a new name. I was still finding myself but I thought that I was out of the woods somehow. I'm not. I took a personal leave from school for unrelated health problems, and I started this androgynous phase- I cut my hair short and wore women's button shirts, vests, boy-cut jeans, bow-ties. And I was HAPPY. I started hormones right before all this. And I thought that I had figured it all out-neutral pronouns, butch clothing, and no need to worry so much about everything, suppression suppression. I thought I had found myself, but lately all of that certainty has just gotten away from me and I feel like I'm drowning.
I'm at my one year mark for hormones today. I remember when I was first discovering this part of myself, when I was just fifteen or sixteen, I had this idea of where I would be when I turned twenty. I didn't think I was being that unrealistic. I wanted to pass, to grow my hair out, and to be able to walk around in public without getting stared at and insulted. I know I must sound like a hypocrite saying this next to a whole plethora of people who want the same things...but I feel like I was so close to reaching these goals, and now here I am, well into year nineteen, and I know that none of this is coming. I should have started sooner, before my bones set and puberty finished up with me. I'm a year into the HRT literally and NOTHING has changed-my skin is a bit softer, and that's it.
I'm going back to school in a few days, and I feel like I'm still not ready. When I took this leave, I told myself "ok, I'm going to find myself" and now that I know exactly what and who I am, I just feel so powerless to act on any of it. I'm transsexual for one thing; I always knew I was transgender, but I never committed to being transsexual until now. I'm finally certain that I want to become the girl I should have been from the day I was born. Now I'm just heading back into the same sixteen-hour-a-day madness and it feels almost like high-school again. Like I can't move forward anymore, not in terms of my transition, and I need to finish that transition if I'm going to survive. Right now, I'm not surviving...I just can't sobbing, I can't sleep, I almost smashed my mirror earlier today. For the first time in my life I know exactly where to go, and don't think I can get there. I don't have a way out.
I'm so sorry to just vent like this, I know I probably sound like a child, but I just can't deal with everything. I have literally no support at all. My folks think I'm crazy, my girlfriend is in her own crisis right now...I'm just totally overwhelmed. I just can't stop crying

Anyhow, thanks for putting up with this; I just need some support right now.
