Craving romance

Lately I've been craving romance, not sex or anything like that. Just cuddling and kissing and holding hands. Also having someone there when I'm sleeping, not creepily, just feeling someone lying next to me. It's gotten to the point where I read fanfiction to give in to these desires. The problem is, that I'm in high school, 10th grade to be exact. I've been told that it's OK if I date, but I'm not ready yet. But I feel like it's because I'm looking too far into the future..... High school relationships almost never last, and I know that I would not be able to break up with someone. So no matter what I do, I will get hurt in the end, either by staying with the person, or by being broken up with. I'm not emotionally ready for that. I'm also dont have the best mental heath right now. Am I being too paranoid? Should I not think of the future and just go for it? I'm also worried of family not being OK with it if I end up dating a girl/gender neutral person (I'm pansexual).
