Someone told that everything is going to be fine. ("is gonna" is slang)

(Should) I feel good now?

Sometimes I dream about you.

I know I did a stupid thing before and I know that it was my fault.

Now I regret it.

Good work. The other sentences are fine. And most importantly I hope you feel better soon!
