You're worth it. I'm worth it. I can't stop thinking about.... (translation)

Question

How do you say the following in Spanish?

You're worth it.

I'm worth it.
(I don't know if it's yo valgo, lo valgo, me valgo.....)

I can't stop thinking about you.
(this stumps me because there are 3 verbs so I don't know what gets conjugated and what stays as in infinitive.)

I like it hot.
(yes, as in caliente). hehe. Since there's an "it" in the english version of this sentence I'm not sure how it translates to Spanish.

Thank you!
