First, the changes are subtle. You might not even be able to tell in a picture because of the basic shape of your face. If you're really low weight, you may not see many changes at all due to the fact that the only part of this that will change is the distribution of fat cells over the facial area. As others have noted, this process takes a long, long time. Generally, all the changes aren't 100% set in until about seven years in, due to cell replication and replacement timelines (you replace every cell in your body every seven years).
Second, you are a horrible judge at judging yourself, just as every one of us is. We all have what's know as 'persistent mental image'. This means that, barring you finally getting used to and inured to what you look like now, you'll still see the 'old' you, no matter what.
I agree with Natalia, most of the changes that made the difference in my life were completely and totally based on what I did *outside* of medical transition. I got my hair done, started taking care of myself, exercising, treating myself right. Once I was in a pretty good place with how I was treating myself, I was able to start going out and making friends and all the rest of the things that life has to offer. Life got way more fun after that.
Oh, and about three years in, I looked at a picture of myself pre-transition and was like "WOAH! Who the hell is THAT?!?" so, you'll get there.
