Someone who constantly worries about a situation and obsesses over the possible outcome of something before it happens. Someone who thinks a lot and dwells on things a lot.
I am worried about how my dress will fit, will he think I am fat?

Do you think I will get in to trouble? I am tweaking on the situation.

What will happen if the judge sends me to jail? I am a tweaker.
