I know I am. I've done a lot of reading about it, and it's actually super common in gifted kids. I am super sensitive to sounds, lights, textures, and smells (and sometimes taste, but getting better at that one) and also super sensitive to emotional situations or signs of displeasure from other people. I have a lot of Asperger's traits but the psychiatrist I saw when I was younger wouldn't diagnose because of my high ability to empathize. So I think a lot of this is innate, but compounded by childhood circumstances.

When I like people (and I like A LOT of people), I want to be close to them and I really, genuinely enjoy their company in a really full way that I don't think other people really experience. I'm really good at just focussing on that one person and just basking in their presence. I feel this way when I'm with my brother or with my closest friends or with some "adults" in my life, and I don't think there's anything WRONG with it, necessarily - I've been this way for as long as I can remember and it just comes with the territory.
