I think, as you mentioned yourself, that your curls is just one more thing
you don't like about yourself. Why do you think yourself unattractive? Sounds to me like you're really bullying yourself, talking yourself down like that.
What's your regimen like now? Knowing what products you're using will be helpful to us. Also, figuring out your hair properties (porosity, texture, etc) will be useful in choosing the right products: Live Curly Live Free - Curly Hair Basics
These properties are a better predictor of what your hair will respond to than curl type.
You say you don't like investing much time in your hair. If spending less time on your hair would make you happy, then try to establish the simplest routine you can. Also, since your hair is long, you may want to consider plopping or diffusing to shorten drying time, or getting it cut shorter. (Plus if you spend less time worrying about your hair, then hopefully you'll spend less time beating yourself up about whether it's perfect or not!) Ask us questions – we're happy to help!
Side note: When I was growing up, I would've given anything to have straight hair. Now that I'm 22 and know how to take good care of it, it's a defining part of my look (in a good way!) and I can't imagine myself any other way. I love my curls.
