Since you are not well versed this, I would get a contractor to look at it.
Basically, the first thing he will look to see is if the ceiling joists are perpendicular to the wall ( very possibly load bearing wall) or parallel to the wall ( probably not load bearing wall.)
However, this is an over-simplified explanation, and sight unseen I would not hazard a conclusive guess. There are other possibilities. A knowledgeable person needs to SEE this.
