I took up an offer to indefinitely extend an internship with some pay, but now I am no longer should if I want it?

It was a three-month internship at a local newspaper that officially ended last week.

They offered me an opportunity to extend my internship, and to pay me for the things that I write.

The pay isn't much, it hardly pays for my gas to commute, but I readily took up the offer.

Now, I am no longer sure if I want the position; I already know that journalism is not quite the career path that I want to move into, but that I still want to work in some sort of communications/media capacity.

What should I do? This all happened last minute, and I didn't really get much time to think about it. I just took it on the spur of the moment.

I would love to talk to my supervisor about this but unfortunately, he is in a place where he cannot readily be reached.

So, I'm stuck here in limbo, half-regretting my decision, left not sure what I am expected to do when I come in this week or how, if at all, the expectations have changed for this new "role". And most importantly, I don't even know if this extra work is worth beyond having my work published (I'm not counting the pay since 1) realistically, it will only be enough to pay for my gas and 2) I'm not even guaranteed to have enough "work" to earn enough to pay my gas).

Regardless of what I decide in the next 48 hours, I still plan on my doing my own thing and searching for other work. I just want to know whether it is worth spending any time on something I'm not entirely happy doing.

Words of wisdom greatly are appreciated.
