I can't stop thinking about my first kiss with my crush. It was weird.
That sucks. Why are you are thinking about the kiss so much?
I just realize that I have to go slowly.
It's good that you let them know how you feel, and as long as they kissed you back, there is hope! You probably feel many emotions, and that is normal. You don't need to brood over it-If it was awkward and weird, you can laugh about it with them later!
I wouldn't say I am brooding about it, but I'm devastated that I feel that way. I don't know what to do now.
Don't be devastated to feel that way about your first kiss. You had never done it before and you have no experience so it will be weird. You will get better at it and it will feel less weird.
