It's definitely possible to become addicted to over the counter medication, both psychologically and physically.

Some of the signs of addiction are:

Constantly thinking about using or where the next drug is going to come from.

An inability to stop taking the drug.

Continued use despite negative consequences to the user.

Tolerance - or needing more of the drug to get the same effect.

Symptoms of physical withdrawl (varies by drug) but definitely having some usually unpleasant physical response when the drug is absent.

Think about this list and how it applies to your life. Only you can decide if you have an addiction or not, but your answers to this list may give you some direction to think about.
