I am disappointed with myself

So yesterday I got my SAT scores back, and I really didn't do as well as I'd hoped to. This disappoints me a lot. Like, I have these huge dreams and aspirations and I'm really ambitious, but now I feel like I don't have enough to back that with. Before I took it, I always just kinda assumed that I would do well enough, but apparently not. It just sorta sucks to see myself to worse than I want to, and it's not like that score is something I can really work at all that much. I don't even really have grades that good, either, and I was banking on my testing scores to make up for that at least a little. Uuuuuggghhh. I don't even know. Hopefully I can do better next time.
